12 Heating minimum on/off time (minutes)
This item is the same as the “Cooling minimum on/off time”, but for the heating system.
The default setting is 8.
13 Stage 2 Differential
This item specifies the temperature difference between stage 1 and stage 2. 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 severe weather conditions. A setting of 1 or 0 is not
recommended. The default setting is 2.
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.
Days - Counting down from 10 - 0
The filter reminder can be disabled by setting this item to 60.
16 System runtime (This week)
This item logs the amount of time (hours) that the heating and cooling system was in operation this week.
17 System runtime (Last week)
This item logs the amount of time (hours) that the heating and cooling system was in operation last week.
