OPERATION
Notes on sensor calculations:
■ If the sensor reading exceeds temperature limits (“HI” or “LO”) then the maximum or
minimum value will be used in the calculation.
■ If all 3 sensors are set to OFF, the Local sensor will automatically be set to FULL.
■ If there is a problem with the installed remote sensors, then the Local sensor reading
will be used for the temperature.
Detection of Remote Sensors:
■ When AC power is present, the thermostat can detect any remote sensors connected. (It
may take up to 30 seconds.) “Found RM1” or “RM2” will alternate with the day display.
■ The maximum distance a remote sensor can be wired to the thermostat is 328 ft.
(100m). For short distances up to 100 ft. (30m), standard thermostat wire will work. For
longer distances, or environments with a lot of RF noise, shielded or twisted pair wire
should be used.
■ If the thermostat has a problem communicating with a remote sensor, then “Check
RM1” or “RM2” will alternate with the day display.
