4.2 Control Type

Control Type, System Mode and Algorithm Configuration

The factory default control type is Heating only. The installer must decide the control type
suitable for the application and set it to the desired function. Control type is only configurable
by the installer using Engineering Mode Menu or BACnet supervisor. To change between the
Heating only and Cooling only control types via BACnet, first set the "Options" parameter
(BACnet point AV37) to a binary "1" in order to enable the changeover action – then within
one minute setting BACnet point MSV1 to Cooling only (1) or Heating only (2). To change
mode locally via the Engineering Menu, first set the OPts bit to "1"- and allow the Engineering
Menu to time out- then QUICKLY press the MODE button followed by the UP or DOWN
button to change mode between heating and cooling mode. Once the Options (OPts E43, or
BACnet point AV37) parameter is set, the operator has one minute to change the mode
(MSV1) between heating or cooling, after which the options parameter is reset to 0, and the
mode is locked.
Occupied Cooling (AV0) or Heating (AV3) set points can be set respectively for cooling only
or heating only control types. This also applies to the Unoccupied Cooling (AV8) or Heating
(AV9) setpoints. Deadband is not applicable in this single mode application.
