In most cases, entering the room will have initiated an HVAC drive cycle after the Sensor detected
occupancy. Possible exceptions:
-If the temperature in the room is within hysteresis of the HVAC setpoint, a drive cycle may not
commence;
-A delay may have been programmed into the EcoSmart VRF Controller thermostat, instructing the
unit to wait for a particular duration before triggering a drive. (Although uncommon, this feature is
sometimes requested by a property. In almost all cases, the delay is less than 3 minutes.)
2. If a drive cycle does not initiate within 5 minutes of entry, force a drive cycle by temporarily
setting the thermostat to some arbitrary high or low temperature (ensure the HVAC mode is
set correctly).
EcoSmart VRF Controller thermostats default to Occupied status if communication with the
Sensor(s) is lost for any reason. This permits the units to continue allowing the occupant to control
the room temperature. However, in this state energy savings will be lost. If in doubt whether the
sensors are associated, re-associate all Sensors per the EcoSmart Firmware 2.x Device Association
Guide.
