I/O SIGNAL DEFINITION
TYPE
Output Digital Indicates the heat/cool or slab system type that has been
selected. Remains high for as long as the corresponding system
is selected.
The thermostats support single-stage and multi-stage heating
and cooling systems, including conventional fossil fuel systems,
heat pumps with auxiliary heat and slab heating systems.
High/1 = System selected; Low/0 = System not selected
Output Digital Indicates the subtype for heating/cooling systems. Remains high
for as long as the corresponding subtype is selected.
Radiant heating turns large areas (floor, walls, ceilings) into large
surface radiators.
Forced air is a type of heating system that uses a blower motor
to move air through the furnace and into the ductwork.
In dual-fuel setups, the auxiliary heat output runs in place of the
heat pump in cold weather.
High/1 = Subtype selected; Low/0 = Subtype not selected
Output Digital Indicates how many stages of cooling or heating there are in the
system.
High/1 = One or two-stage system; Low/0 = System type not
selected
Output Digital Indicates that dual-point auto mode has been enabled. Remains
high for as long as the mode is enabled.
High/1 = Dual-point auto mode enabled; Low/0 = Not enabled
Output Digital Reports whether Auto Mode is permitted in the system. If
enabled, the thermostat will not display Auto on the System
Mode screen and will not permit the thermostat to enter the auto
mode even from Cresnet commands.
High/1 = No Auto Mode; Low/0 = Auto Mode permitted
Output Digital Indicates that wide range cool mode has been enabled. Remains
high for as long as the mode is enabled.
Wide range cool extends the cool setpoint range to the full auto
range of 38° to 99°F, or 3° to 37°C. This is suitable for wine
cellars or other colder chilling processes.
High/1 = Wide range cool enabled; Low/0 = Not enabled
Output Digital Indicates that Run Fan in Heat Calls has been enabled. Remains
high for as long as the mode is enabled.
Run Fan in Heat Calls is a device setting that activates the fan
output with W1/W2 heat calls. Does not enable operation on slab
systems on the slab (W1) call.
High/1 = Run Fan in Heat Calls enabled; Low/0 = Not enabled
