12 Heating minimum on/off time (minutes)
Same as Cooling minimum on/off time, for the heating system.
The default setting is 8.
13 Stage 2 Differential
This item specifies the temperature difference between stage 1
heating (the heat pump) and stage 2 heating (auxiliary heat). The
default setting of 2 (degrees F) is recommended for all applications.
In special cases a setting of 3 or 4 may be used when precise control
of temperature is not as important as highest energy efficiency,
however, the thermostat will not be able to maintain temperature
within 1 degree of its setting under cold weather conditions. A
setting of 1 or 0 is not recommended.
In this thermostat, the automatic anticipator will compensate for the
temperature "droop" caused by the stage 2 differential under cold
weather conditions.
14 Clock adjust
If the clock on the thermostat is running faster or slower than the
actual time, you can have the thermostat automatically compensate up
to 29 seconds per day. The thermostat will add or subtract the
selected amount of time daily.
(1 = - 29 to 59 = + 29 - Seconds per day - 30 = No change)
The default setting is 30.
Note: If an HAI automation system is being used, the controller
system time is sent to the thermostat every minute. This adjustment
will have no effect.
15 Filter reminder
The thermostat logs the amount of time the system fan has been
running. When this setting reaches 0, the thermostat will display a
reminder to replace the filter. The setting is the amount of days (24
hours of system operation) before this reminder is displayed.
