Option A
Setting minimum heating temperature set point
This feature allows the building owner to determine the minimum heating temperature available to the user.
Option b
Setting maximum cooling temperature set point
This feature allows the building owner to determine the maximum cooling temperature available to the user.
Option C
Optimum start control, heating (OSC)
(not available if "Non-Prog" is selected on DIP switches 1 & 2)
This feature allows the installer to enable the optimum start control for the heating event. If enabled it allows the heating
to be turned on earlier than the programmed time in order to ensure that recovery of room temperature is achieved by the
programmed time. The setting is dependent upon the capacity of the system and the building heat gain/loss characteris-
tics and can be determined from the following table. If Option 4 (occupancy and smart-fan programming) has been
enabled, the optimum start control will operate at each occupied event change that requires an increase in temperature.
If Option 4 has been left in the disabled mode the optimum start controller will only function prior to the first event (Event
1) of the day
Option d
Optimum start control, cooling (OSC) (not available if "Non-Prog" is selected on DIP switches 1 & 2)
This feature allows the installer to enable the optimum start control for the cooling event. If enabled it allows the cooling
to be turned on earlier than the programmed time in order to ensure that recovery of room temperature is achieved by the
programmed time. The setting is dependent upon the capacity of the system and the building heat gain/loss characteris-
tics and can be determined from the following table. If Option 4 (occupancy and smart-fan programming) has been
enabled, the optimum start control will operate at each occupied event change that requires a decrease in temperature. If
Option 4 has been left in the disabled mode the optimum start controller will only function prior to the first event (Event 1)
of the day.
Option E
Setting thermostat calibaration
This feature allows the installer to calibrate the temperature shown in the LCD display by ± 3°F.
