Highrise Smart Thermostat & Heating/Cooling FAQ

Conventional thermostats simply adjust the temperature in your home. Programmable thermostats let you set the temperature based on the time of day. What makes smart thermostats "smart" is their ability to program themselves.They learn from your living patterns and adjust accordingly. You can control the climate from your mobile device and even view your consumption statistics in real-time. The “smart” adjustments of the thermostat keep your furnace running as efficiently as possible, which can help avoid unnecessary wear and tear and keep your energy costs down.

Nest and Ecobee are among the leading smart thermostat brands on the market today. To compare the two options side by side please follow the link on the side bar of the home page titled "Need Help Selecting a Thermostat?"

Typically thermostats only read the temperature where they are physically located. Remote temperature sensors can be placed in other areas to allow your smart thermostat to know which room should be a certain temperature at a certain time of day. If you find that the temperature varies a lot from room to room then these are a great solution.

Yes! There are range of Wall Plate color and style options for your thermostat. These can be added to your order via NextechSelect. The standard included style is white plastic. The wall plates are able to cover the footprint of the thermostat replacement on the wall. Be advised however, that if your unit was painted that there is a chance that touching up could be necessary around your new thermostat. As an alternative to touching up, we offer fully customized made to order wall plates that are larger and better equipped to cover the entire area. Please reach out through https://shop.nextechenergy.com/pages/custom-quote or call us for pricing and availability.

 Ecobee thermostats are black. The Nest E comes in white. The Nest 3rd Gen standard color is stainless steel although it also comes in white, black, or copper. However, please be aware if you select a color other than stainless steel there may be a delay in delivery and installation. 

Yes! Nextech installed thermostats are fully compatible with a range of smart home integrations such as Amazon Alexa, Google Assistant, Apple HomeKit, Works with Nest, and IFTTT among others.

You can customize your thermostat order via NextechSelect to include a variety of smart home products including cameras, wi-fi routers, smoke detectors, and more. Programming and integration is always included with your install. 

Technically no. If not connected to Wi-Fi or the internet, the device will work as a manual thermostat. However it must be connected to be used remotely on your app and to access many of its features. Most likely you will want to connect it.


The device should connect anywhere there is WiFi, however particularly weak WiFi could have trouble connecting, and a small number of routers (typically older ones) are not compatible. 


If your current WiFi router or connection is a concern, Nextech sells and installs the latest high speed modems, routers, and mesh networks to improve your internet speed and performance.

Nextech handles all of the initial setup and programming of your smart thermostat.

Yes, smart thermostat settings may be changed or modified at your discretion.

The Auto-Scheduling feature is how your smart thermostat learns from your behavior and past patterns and sets the temperature accordingly. For example, if you routinely turn the temperature down at bed-time, you may notice the thermostat begin to do this automatically on your behalf.


For users with inconsistent work/home schedules or patterns of use, you may consider disabling the Auto-Scheduling feature. You can manage auto scheduling in your thermostat’s settings.


Initial programming of your device is unique to your HVAC system. We highly recommend that you contact us prior to resetting to ensure the device still functions properly upon restart.


The thermostat will display the temperature it is reading from its location, which may be different from other parts of your home. This discrepancy is fairly common, particularly in high-rise condos and is nothing to be alarmed about. Some causes of this could include (but are not limited to) the thermostats close proximity to supply air vents, sunlight through windows causing a green house affect, or the thermostat being located near another source of ambient heat such as your unit’s hot or cold water coils and pipes.

You can resolve this false temperature reading at the thermostat by adding remote temperature sensors. This allows you to drive the fan coil from a another point in the room. You can purchase temperature sensor from our store here


If you plan on removing your thermostat from your account we recommend notifying Nextech to ensure the device continues to function correctly. 


The smart thermostat accounts will be password protected and can offer two factor authentication. Be sure to create a strong password for your thermostat and not to share it with any unauthorized parties. It is recommended that the password you choose be dissimilar to other existing passwords for your personal devices and accounts.

Yes! For Nest, adding family and friends to your account is done through the Google Home App, so if there will be other individuals given access to the Nest be sure to download the App and set up a Google account. If you have an Android phone or a gmail account, you already have one that you can use.

Nextech’s labor warranty is 90 days from the installation date. The thermostats come with a manufacturer’s warranty that covers the device and certain products may include an extended warranty when they are purchased directly from Nextech.


See https://shop.nextechenergy.com/pages/terms-of-service for details.


Nextech provides the initial set up and demonstration for your device. Your resource for support going forward will be the product’s manufacturer (Nest, Ecobee, etc.) Their customer support and online resources are well equipped to answer your questions.


Most furnaces typically need to change the air filter once or twice a year to keep the systems running smoothly. If you enable Filter Reminders, your thermostat will let you know when it’s time to change your filter based on how long your system has been running.


If your building management provides this service on your behalf you can disable or disregard the air filter notifications.


For basic troubleshooting and programming matters please reach out to your device manufacturer’s customer support. If you believe your issue is related to your unit’s HVAC system ie: motor, valves, fan coil, etc. you should contact your building’s engineer for assistance. If these steps have not resolved your issue or you believe the matter is directly related to the installation, please contact us.

A fan coil unit is a simple device consisting of a fan and a heating/cooling exchanger or 'coil'. It is part of an HVAC system commonly found in residential, commercial, and industrial buildings. A fan coil unit is used to control the temperature in a localized space where it is installed by blowing air through connecting ductwork. It is controlled either by a manual on/off switch or by a thermostat, which controls the flow of hot or cold water to the coil using a valve actuator and fan speeds. Larger spaces may include several fan coil units to heat/cool the various living zones.


Due to their simplicity and flexibility, fan coil units can be more economical to install than ducted 100% fresh air systems (VAV) or central heating systems with air handling units or chilled beams, especially in high rise and multi-tenant buildings. Various unit configurations are available, including horizontal (ceiling mounted) or vertical (floor mounted).


Fan coils and electric baseboards common in high-rise buildings work with line-voltage thermostats which can be either 120 or 240 volts. Smart thermostats by comparison use 24 volts. If you tried to hook up a low voltage thermostat directly to a fan coil unit it would fry the thermostat. Nextech converts high voltage systems to a lower one with a prefabricated conversion kit. This requires specialized equipment used by a certified technician.

Depending on the make and model, fan coil units typically support between 1-3  fan speeds: low, medium, and high. These speeds dictate how fast the heated or cooled air flows into a given space.


Nest 3rd Generation thermostats are able to support up to three fan speeds. These speeds can be manually toggled. Nest is also capable at choosing the optimum speed for you based on your desired temperature, allowing for a totally hands-off approach. The Ecobee4 comes with capability for a single fan speed that will be chosen at the time of programming. In certain cases the Ecobee4 may be able to support a second a speed which can be programmed for an additional add-on fee, but the two speeds may not be manually toggled. The Ecobee will automatically choose between the two speeds.


The Nest E and Ecobee3 Lite thermostats are limited to one fan speed, chosen at the time of programming.


Valve actuators are connected to your building’s HVAC piping and allow the thermostat to control the heat/cool by opening and closing the hot and cold water valves. The motor activates the fan and controls the speed. 


Nextech will examine and test your valve actuators and motor prior to the thermostat installation and notify you of any deficiencies found. Defective, aging, and/or inoperable valves and motors can adversely affect the proper function of your thermostat. In many circumstances Nextech is able to quote to replace aging and or deficient motors and actuators to ensure the best possible function of your system. You may wish to consult with your building’s engineer or maintenance person if an issue is found and a component in your system needs to be repaired or replaced, as some buildings provide this service to residents themselves.


You may notice that if you like to keep it cool inside even when it’s a bit colder outside that the thermostat isn’t blowing cold air when you turn the temperature down, despite the fan running. This may be because of certain changes that many high rise buildings make to their heating and cooling systems when the seasons transition.


Depending on whether your building has a 2-pipe or 4-pipe system, you may find your ability to cool reduced in the winter time. Two pipe systems typically cannot support both heat and cool simultaneously. Therefore, attempting to run the AC during the heating months will be ineffective as well as inefficient. If you believe you have a 2-pipe system, do not use the “auto” heat/cool feature of your thermostat. If unsure of whether you have a 2-pipe or 4-pipe system, check with your building’s engineer or maintenance person.


In general, the majority of fan coil models do not have humidifiers built in. There are some exceptions, and certain buildings have separate humidifiers with a local humidistat controller installed at the fan coil unit.

If your unit has a built in humidifier, Nextech may be able to integrate the humidifier with the thermostat and eliminate the need for a separate humidistat. This is typically a custom quoted service unique to your specific unit. If you think you may qualify for this service contact us directly for more details.
