Turning On Comfort Recovery; Axlink Communications Screen; Switching Axlink Devices - AMX ENV-VST-C Instruction Manual

Turning on Comfort Recovery

Comfort Recovery enables you to indicate whether the heating/cooling system recovers gradually from an energy-saving setpoint
temperature to a comfort setpoint temperature. By incrementing the setpoints gradually, the heating/cooling system activates in
advance of the actual set program time so the area is at the desired temperature at the start of the program time.
Comfort Recovery begins two hours before the next programmed setpoint. During the Comfort Recovery period, every 15 minutes
the thermostat computes the difference between actual room temperature and the desired temperature of the next setpoint and set
the setpoint to the halfway point between the two.
For example, if the room temperature is 60 and the next setpoint is 70, Comfort Recovery begins and the thermostat moves the
setpoint to 65. Fifteen minutes later, the thermostat checks the setpoints again and finds the room temperature is 63 and the next
setpoint still at 70, so it changes the setpoint to 66. Fifteen minutes later, the thermostat checks the setpoints again and finds the
room temperature is 66 and the next setpoint still at 70, so it changes the setpoint to 68.
NOTE: Comfort Recovery only works when moving forward between Sleep and Wake states and between Leave and Return states.
When using Comfort Recovery between Sleep and Wake states, the thermostat uses the Sleep setpoint from the previous day and the
Wake setpoint from the current day.
If this option is disabled, heating/cooling setpoints are changed at the exact start time of the program period. Perform the
