"Revers Valve O/B"
Default:
Range:
o
o, b
This option appears only if you have selected
ON
at Step 12, "Heat Pump Option". Set the mode in which the reversing valve is
energized; cooling mode (o) or heating mode (b). The cooling
symbol is displayed if you select
o
and heating symbol is
displayed if you select
b
.
"EMH Output"
Default:
Range:
dIS (Disable)
dIS (Disable), ENA (Enable)
This option appears only if you have selected
ON
at Step 12, "Heat Pump Option". Select
ENA
to enable emergency heat (EMH)
outputs W1 and W2, and the EMH option via the Control Mode (see page 30). Select
dIS
to disable EMH availability. The heating
symbol is also displayed.
If you select
dIS
, Step 15
"EMH Auto Mode" will not be available.
If you select
ENA
, Step 15
"EMH Auto Mode" will be available.
"EMH Auto Mode"
Default:
Range:
NO (Disable)
YES (Enable), NO (Disable)
This option appears only if you have selected
ENA
at Step 14, "EMH Output". If you select
YES
, the emergency heat (EMH)
will be operational in Automatic mode. If you select
NO
, the EMH will not be operational in Automatic mode. The heating
symbol is also displayed.
Valve Settings
“Valve Size”
Default:
Range:
1”
1/2”, 3/4”, 1”
Select the desired valve size in inches for the 6-way valve from the available options.
Analog Output 2 (AO2)
"AO2 Ramp"
Default:
Range:
Hr1 (Heating Ramp 1)
Cr1, Cr2, Hr1, Hr2 (heat with fan), Hr2 (heat without fan), CH1, HU, CO2, 6w, dto, VFdt, VFd
P
, FAN,
OFF, COr
Select the desired signal from the available options.
•
Cr1 (Cooling Ramp 1) or Cr2 (Cooling Ramp 2). The Cr1 and Cr2 ramps are used for cooling. If selected, the controller
performs cooling based on the cooling proportional, integral, and dead band values.
•
Hr1, Hr2 (heat with fan), or Hr2 (heat without fan). The Hr1 and Hr2 ramps are used for heating. If selected, the controller
performs heating based on the heating proportional, integral, and dead band values.
•
CH1 (Cooling and Heating). If selected, the controller performs cooling regularly. If another output is set to heat, it
performs heating regularly.
•
HU (Humidify). If selected, the controller modulates the output based on the humidify demand.
•
CO2 (Carbon dioxide). If selected, the controller will activate or deactivate the output based on carbon dioxide levels.
•
6W (6-way Valve). If selected, the controller will modulate the 6-way valve depending on the heating or cooling demand.
•
dto (Delta temperature control). If selected, the controller will modulate the
ΔT control based on the inlet and outlet
temperature of the water inside the fan coil unit.
•
VFdt (VFD Temp Loop). If selected, the controller will modulate the VFD fan based on the selected temperature input.
•
VFd
P
(VFD Pressure Loop)
.
If selected, the controller will modulate the static pressure based on the reading and the
pressure setpoint.
•
FAN. The FAN option is available only if you selected OFF at Step 12, "Heat Pump Option". If selected, the controller
modulates the output based on the Fan demand.
•
OFF. If selected, the controller does not use the output.
•
COr (Changeover). If selected, the controller will modulate heating and cooling, as appropriate.
If you select
OFF
, Steps 18 to 20 will not be available.
If you select
VFdt
or
VFd
P
