Re-associate all sensors.
Procedure: Functional Inspection
1.
Observe whether the HVAC system is operating (e.g. drive cycle) after entering the room.
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 Ec 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).
Ec 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.
