Energy Savings While in the Away Mode

Provide energy savings in the

Away mode by maintaining

the temperature at a lower

heating setpoint and a higher

cooling setpoint.

When armed to Away the system will interrupt control power to the existing mechanical

thermostat and turn the HVAC system off. Control power is restored to the thermostat when the

temperature drops to the TS16 low limit setpoint or rises to the high limit setpoint allowing the

HVAC system to turn on and bring the temperature back to within the low and high limits. When

the system is disarmed control power will be restored to the thermostat and the temperature will

be maintained at its heating and cooling setpoints.

1) Arming the system to Away sends an ON command to Control Channel 1 energizing relay 1

on the EXP8 expansion board and interrupting control power to the thermostat.

2) When the temperature drops to the TS16 low limit setpoint or rises to the TS16 high limit

setpoint an ON command is sent to Control Channel 33 energizing relay 2 on the EXP8

expansion board and restoring control power to the thermostat.

3) When the temperature rises 2 degrees higher than the TS16 low limit setpoint or drops 2

degrees lower than the TS16 high limit setpoint an OFF command is sent to Control Chan-

nel 33 once again interrupting control power to the thermostat.

4) Disarming the system sends an OFF command to Control Channel 1 restoring power to the

thermostat which will maintain the temperature at its heating and cooling setpoints.

Note: Once control power has been interrupted to the thermostat, the delay-

on-break relay will prevent control power from being restored to the

thermostat again until the minimum off time of 4 minutes has elapsed.

This will help prevent short-cycling which could damage the HVAC unit.
