Turning On and the Heating System
In the heat mode, the relay is operated to maintain the temperature of the zone.
The control output will turn on when the sensor temperature falls to the setpoint
temperature minus half the differential amount. The control output will turn off as
the temperature rises to the setpoint plus half the differential amount.
During the normal operating mode:
To disable or enable the relay output, press the power button once(eg. 1
second). LCD indicates a flashing “Heat” or “Off” under the “System”
heading. Press the power button again to toggle between “Heat” to enable
and “Off” to disable the relay output. After 30 seconds, the system returns to
normal operating mode.
To completely power off the thermostat, press the power button for three
seconds. Press the power button again to turn back on the thermostat.
