For around $300 you can get a NEST smart Thermostat. Compatible with most of heating / cooling system in the market and supports multi zone. Smart phone controlled over internet. Much better than traditional du妹妹y ones.
Check the back of your old controller - Nest Thermostat needs at least 3 wires - if there are only 2 wires then you need to re-run the control cable to the main heating unit even your heater system is compatible with it. |
