What is a smart thermostat?

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.

What is Line Voltage Conversion?

Fan coils and electric baseboards common in hi-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.

What is a remote sensor? Do I need one?

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.

My thermostat temperature reads much higher than it actually is in the room. What is causing this?

This may be caused by a “Greenhouse Effect” ie: the sun shining through a window directly onto your thermostat and warming it. The thermostat will display the temperature it is reading from its location, which may be different from other parts of your home. You may be able to reduce this effect through your device’s advanced settings and by utilizing remote sensors.


What steps should I take if I believe my thermostat isn’t functioning correctly?

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.


What happens if I need to remove my thermostat from my account?

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