Table 1. Default Program.
F. Setpoint Recovery
from Not Occupied
to Occupied: The thermostat shall incorporate a ramping feature that gradually changes the space setpoints.
During recovery operation, the setpoint changes at a rate in degrees per hour depending on the
outdoor air temperature. If there is no outdoor air temperature sensor available, the minimum ramp
rate is used. A PDA can be used to individually adjust ramp rates for heating and cooling.
G. Fan Operation: Fan operation shall be selectable as follows:
a. On: Fan operates continuously in occupied mode, and during standby modes, and during a
call for heat or cool.
b. Auto: Fan is energized with calls for heating and cooling.
H. Minimum Stage
Operation Time: a. Minimum On: Heat - 1 minute; Cool - 3 minutes.
b. Minimum Off: Cool & Heat Pump - 1 minute.
I. Power Interruption: a. On loss of power, the thermostat shall maintain programmed times and temperatures for 10
years.
b. Clock and day information shall be retained for a minimum of 48 hours.
J. Overrides: a. The Temporary Occupied Override can be used when the thermostat is in Not Occupied or
Standby mode. It shall switch to the Occupied mode for an installer-configured number of
hours. The default shall be three hours.
b. The Temporary Not Occupied Override shall fix the schedule to operate in Not Occupied
mode for a number of days (between 1 and 99) without changing programming saved in
memory.
c. Pressing “Run Schedule” shall cancel the overrides and return to the program.
