HEAT MASTER REFERENCE — The  Heat  Master  Refer-

ence point displays the occupied low set point, if occupied, or

the unoccupied low set point, if unoccupied. The set point off-

set (if applicable) is calculated into the value.

HEAT SUBMASTER REFERENCE — If heat is enabled,

the Heat Submaster Reference point displays the desired sup-

ply air temperature calculated to heat the space. This is a result

of the heating PID loop calculation.

COOL MASTER REFERENCE — The  Cool  Master Refer-

ence point displays the occupied high set point, if mode is oc-

cupied, or the unoccupied high set point if mode is unoccupied.

The set point offset (if applicable) is calculated into the value.

COOL SUBMASTER REFERENCE — If  cooling  is  en-

abled,  the Cool Submaster Reference point displays the de-

sired supply air temperature calculated to cool the space. This

is a result of the cooling PID loop calculation.

COOLING 

IN 

EFFECT 

— 

The Cooling In Effect point

shows if there is a demand for cooling in the space. The space

temperature must be above the Occupied High or Unoccupied

High set point.
Cooling in Effect: Display Range 

No/Yes

Default Value

No

Network Access None

HEATING IN EFFECT — The Heating In Effect point shows

if there is a demand for heat in the space. The space tempera-

ture must be below the Occupied Low or Unoccupied Low set

point.
Heating in Effect: Display Range 

No/Yes

Default Value

No

Network Access None

REHEAT IN EFFECT — The Reheat in Effect point shows if

the fan coil is in a dehumidification mode and attempting to re-

heat the dehumidified air to maintain the space temperature. If

Reheat is enabled, the zone controller will fully open the cool-

ing valve, if the space temperature is above the heating set

point. Simultaneously, it will modulate the heating valve to

raise or maintain the space temperature at the configured occu-

pied cooling set point during dehumidification.

CHANGEOVER TEMPERATURE — The Changeover Tem-

perature point displays the value from the changeover sensor

(water temperature sensor attached to the two-pipe water loop)

for the fan coil. The Changeover Temperature value is forcible.

It may be received through CCN from a Comfort Controller

that monitors the water loop temperature and provides control

of boilers and/or chillers.

Display Range

–40.0 to 245.0

Default Value

–40.0

Network Access Read/Write

CHANGEOVER STATUS — Applicable to two-pipe heating/

cooling systems, the Changeover Status point determines

whether the temperature indicated by the changeover sensor

will allow the fan coil to provide heating or cooling operation.

The value is determined from the changeover temperature sen-

sor reading as:

<65 F = COOL
>80 F = HEAT
between 65 and 80 = last active status
Changeover Status is forcible. It may be received through

CCN from a Comfort Controller which monitors and maintains

the water loop temperature.
NOTE: This value defaults to HEAT if a changeover sensor

failure occurs or for non-changeover systems.

LINKAGE THERMOSTAT — The following Linkage Ther-

mostat points display the standard values received from a Link-

age Thermostat (if one is being used to provide space tempera-

ture, set point and occupancy information) for this fan coil.

The Linkage Status point displays the status of the linkage

broadcasts from the Linkage Thermostat. A value of 0 is nor-

mal communication. A value of 1 is communication failure. A

value of 2 is not configured. A value of 3 is a change in com-

munication status between supervisory and equipment.
