FREQUENTLY ASKED QUESTIONS

No. Each thermostat can only be controlled by one Portable Comfort Center. But you can connect up to 16 different thermostats to one Portable Comfort Center to easily control multiple zones.

Yes. When connected with an Outdoor Sensor, select thermostats and devices will display the outdoor temperature and humidity on the screen.
The thermostat has a feature called Adaptive Intelligent Recovery(AIR) or Smart Response or Early Start. This allows the thermostat to "learn" how long the heating and cooling system will take to reach the programmed temperature settings. So the temperature is reached at the time you set.
There are several items you can check. First check that the thermostat is set to the Cool position. Make sure the temperature is set lower than the Inside temperature reading. Also check the circuit breaker and reset if necessary. Make sure that the furnace door is closed securely. If “wait” is in the screen or “cool on” is flashing – wait 5 minutes for the system to safely respond. The thermostat will indicate it is asking for the cooling to turn on when "cool on" or a "snowflake" in the display. If this message is in the display, the thermostat is asking for the heat to be on and there is a likely a problem outside of the thermostat preventing the cooling from running.
