When "Pipe Number" is set to 2 and UI19 is set to COC-NH, COC-NC or COS the "Sequence of
operation" is as follows:
"Cool only" or "Heat only" will be determined by the UI19 contact status or sensor temperature.
For Two-Pipe application (no reheat): set "Sequence of operation" to "Cool only" or "Heat only"
For Two-Pipe application (with reheat): set "Sequence of operation" to "Cool-rht" or "Heat-rht"
Choices: Cool only, Heat only, Cool-rht, Heat-rht, Cool/Heat and Cl/ht/rht
Time interval between valve samples. Will open valve for a short period adjusted by "Purge
open" parameter to sample pipe temperature to decide between heating or cooling mode.
Adjustable: 0 to 4 hours (0 hours disables the function)
Time the valve opens to sample pipe temperature to decide between heating or cooling mode.
Adjustable: 1 to 3 minutes
Sets the source of the indoor room temperature. This parameter allows the user to designate
either the Room Controller or any of the bound wireless devices that support temperature to act
as the source for the room temperature.
Wired: sets the thermistor connected to UI20 (RS) as the source to report room temperature.
Internal: sets the Room Controller as the source for the room temperature.
WL 1 to WL 10: sets the selected wireless ZigBee PRO device as the source for the room tem-
perature. Only one device can be selected.
The Room Controller uses the internal temperature sensor only if UI20 (RS) terminal is empty. If
a valid temperature sensor is connected to UI20 terminal, the Room Controller will automatically
disable its internal sensors (Internal, WL1 to WL10) and use the remote sensor as the control point.
Disconnecting the sensor, or if the sensor is faulty, the Room Controller will automatically re-enable
its internal temperature sensor.
Choices: Internal, Wired, WL1 to WL10
