tN4 Features SECTION R
When the setpoint control is connected to a tN4 system,
the setpoint control has additional features not present
when operating alone.
tN4 Bus
When connecting the setpoint control to a tN4 system, there
may be several tN4 busses available. The setpoint control
should be connected to the tN4 bus that best represents the
water temperature required for the setpoint load. Typically,
the setpoint control should be connected to the boiler tN4
bus for Application Modes 2 (Hot Tub) and 3 (DHW Tank).
Typically the setpoint control should be connected to a mix
tN4 bus for Application Mode 5 (Floor).
Heat Source
When the setpoint control is part of a tN4 system, the Heat
Source item in the Adjust menu allows the setpoint control to
inform the tN4 system control whether the heat is hydronic
(HYDr) or provided by another (OTHr) heat source.
Exchange Supply
When the setpoint control is connected to a tN4 system
control and Heat Source item is set to hydronic (HYDr),
the setpoint control requests that the Exchange Supply
Occupied water temperature be maintained on the tN4
bus whenever Relay 1 is heating the setpoint load during
set to the number of days. Once the number of days have
elapsed, the thermostat automatically changes from the
Away 2 scene to the previous permanent scene.
