2-Pipe; 3-Pipe (4-Pipe) - Danfoss CF-RC Instruction

Instruction

6.1.5.1 2-pipe

Menu  Setup  Service  Heating/Cooling  2-pipe: Select 2-pipe to configure auto-
matic heating/cooling for a 2-pipe system.
Select Change-over Low or Change-over High to set change-over temperatures. Settings
must be between 10 and 50°C with a min. difference of 4°C.
6.1.5.2 3-pipe (4-pipe)
Menu  Setup  Service  Heating/Cooling  3-pipe (4-pipe): Select 3-pipe (4-pipe) to
configure automatic heating/cooling for a 3-pipe (4-pipe) system.
• Mode: Set the heating/cooling mode to Auto, Heating or Cooling.
• Master room: Select which room should be the Master room. Only rooms with a CF-RD
room thermostat are listed and selectable.
• Neutral zone: Set the Neutral zone parameter to 2K or 4K.
• Number of outputs: Set number of outputs to 0, 2 or 4 (options for 2 and 4 outputs are
only selectable, if all 2/4 outputs are connected to actuators and not already in use).
4 outputs on Master Controller must be configured as outputs for 3- and 4-pipe sys-
tems (if the system contains more Master Controllers, all outputs must be from Master
Controller 1).
Outputs for 3- or 4-pipe systems are:
• Output 1: Warm water supply (used in 3- and 4-pipe systems).
• Output 2: Cooling water supply (used in 3- and 4-pipe systems).
• Output 3: Warm water return (used in 4-pipe systems).
• Output 4: Cooling water return (used in 4-pipe systems).
