Vacation Hold
1)
The thermostat can be set to hold a single specific temperature for up to
30 consecutive days. Upon activation, the thermostat will hold the
temperature until the duration period times out at which point the
thermostat will return to program mode. To activate this feature, depress
the
VACATION
key. The LCD will display the duration in days and the
set point temperature.
2)
Use the red/blue arrow keys to adjust the set-point temperature to the desired level.
3)
Depress the
TIME/DAY
key to select the duration of the hold period (up to 30 days). After 10 seconds from
the last touch of a key, the thermostat will store the setting and the LCD will return to its normal setting.
NOTES: To view the time remaining on vacation hold during normal operation, depress the
VACATION
key at
any time. To leave vacation mode and return the thermostat back to normal program mode at any time,
depress the
RUN
key for 1 second.
Understanding Additional Features
•
Efficient Recovery Mode:
This feature minimizes the use of the auxiliary heating / 2nd stage heating or
2nd stage cooling during the recovery from temperature setback periods. Efficient Recovery Mode activates
when heating or cooling is called upon by the program to bring the room temperature to a desired level.
Instead of using both heating or cooling stages to accomplish this, the system will use only one stage by
turning on earlier and slowly reaching the desired temperature setting. Note: This feature can be deactivat-
ed by changing the ERM switch on the circuit board to off.
•
2nd Stage Cooling/Heating (auxiliary heat):
The second stage heat or cool will automatically be initiated
when the thermostat detects that the system is unable to maintain the desired room temperature. With both
stages of heating or cooling activated, the system has greater capacity to provide the desired level of com-
fort. The second stage is activated when the room temperature moves beyond the first and second stage
temperature differential settings. When the second stage is activated, the AUX lamp will illuminate on the
thermostat faceplate. NOTE: The first stage differential is adjustable [see Temperature Differential section]
and the second stage differential is fixed at 2 F (1 C). AUX lamp feature will only operate if the thermostat is
powered by 24VAC.
