Table 1 describes the combination of
communication requests, the
hardwire input and the 'ON'
(occupied)/'CANCEL' (unoccupied)
push buttons on the zone sensor
upon the occupancy state of the
control.
Setpoint operation
The controller has three sets of
possible heating and cooling
setpoints:
• Occupied
• Occupied standby [network
application only]
• Unoccupied
Occupied setpoints are calculated
from the local setpoint given by the
local zone sensor (thumbwheel)
when present, communicated from
the BMS or the controller can use his
own default values if two first are not
present.
From the local setpoint, they are
calculated as following:
Occupied heating setpoint = Default
occupied heating se offset
Occupied cooling setpoint = Default
occupied cooling se offset
with offset = local setpoint - ((default
occupied cooling se default
occupied heating setpoint)/2)
Occupied standby setpoints are also
calculated from the local setpoint
with the following formula:
Occupied standby cooling stp =
Default occupied standby cooling
se offset
Occupied standby heating stp =
Default occupied standby heating
se offset
Unoccupied setpoints are stored
values (factory-downloaded) (see
default values).
