BOILER MODULATION
SECTION G
Current percent modulation of the boiler’s burner. The boiler modulation increases
when the boiler supply is less than the boiler target. The boiler modulation
decreases when the boiler supply is greater than the boiler target.
Note:
This item is only available when the BOIL TYPE setting is set to 0-10 or 4-20.
– – –, -22 to
266°F
(-30 to 130°C)
MIXING
SECTION D
Current mix supply water temperature as measured by the mix sensor. The control
operates the variable speed pump so that the mix supply is equal to the mix target.
“– – –” is displayed when no mix sensor is available.
Note:
This item is only available when a mix water temperature is selected.
– – –, 35 to
200°F
(1.5 to 93.0°C)
MIX TARGET
SECTION D
The temperature the control is currently trying to maintain at the mix sensor. The mix
target is calculated based on the outdoor design and mix design settings. “– – –” is
displayed when no heat is required for mix zones.
Note:
This item is only available when a mix water temperature is selected.
– – –, -22 to
266°F
(-30 to 130°C)
TANK
SECTION D
Current tank supply water temperature as measured by the tank sensor. The control
operates the heat pump and backup so that the tank supply is equal to the tank
target. “– – –” is displayed when no tank sensor is available.
– – –, 35 to
200°F
(1.5 to 93.0°C)
TANK TARGET
SECTION D
The temperature the control is currently trying to maintain at the tank sensor. The tank
target is calculated based on the outdoor design and tank design settings. “– – –” is
displayed when no heat is required for tank zones.
– – –, -22 to
266°F
(-30 to 130°C)
DOMESTIC HOT WATER
SECTION F
Current Domestic Hot Water tank temperature as measured by the optional DHW
sensor. If the DHW tank temperature falls 6°F (3.0°C) below the DHW Occ setting,
a DHW call is created and the tank is heated. “– – –” is displayed when no DHW
sensor is available.
Note:
This item is only available when a DHW sensor is installed and DHW Mode
is set to 1 to 5.
– – –, -22 to
266°F
(-30 to 130°C)
HEAT PUMP
SECTION E
Current heat pump return water temperature as measured by the HP Return sensor.
The control operates the heat pump when the HP Return temperature is below the
HP RETURN MAX setting in heating and above the HP RETURN MIN setting in
cooling. “– – –” is displayed when no heat pump return sensor is available.
– – –, -35 to
273°F
(-37 to 134°C)
DEW POINT
SECTION C
Highest dewpoint of all network humidity sensors. “– – –” is displayed when no dew
point sensor is available.
Note:
This item is only available when a humidity sensor has been detected on
the network and the access level is set to installer.
SYSTEM IN AWAY
The heating system is in the Away scene. The DHW tank will not be heated.
Setpoint calls are still responded to.
Use the User Switch to change scene out of Away.
PURGING HEAT
Heat is being purged from the storage tank and the heat pump is not allowed to
come on. This may continue for up to 30 minutes and then precool will begin.
