Selecting The Master - Swegon Kit CPT TAC3 Manuel D'installation

1) Principle of wiring
Attention: This wiring schematic is for TAC fans only. For pTAC fans please consult appendix 2.
The CPT TAC3 kit is made of one CBr4 TAC3 CPT (remote control) and one CPT TAC3 (main board).

2) Selecting the master

2 possible configurations (see wiring schematics  appendix 1):
1) The CBr4 (main board) is master : contact between terminals IN1 and +12Vdc on the CBr4 TAC3 CPT is closed.
The entries on the CBr4 TAC3 CPT are active to actually control fans.
The CPT allows:
- to set up,
- to show all the parameters via the display and the LEDs,
- to control 5 external relays (via the 5 relay control knobs, knobs OFF / I / II / III are inactive).
2) The CPT (remote control) is master: contact between terminals IN1 and +12Vdc on the CBr4 TAC3 CPT is open.
The CBr4 TAC3 CPT is passive. In this case it is used only as a connection between the CPT and the fans.
The CPT allows :
- to configure,
- to show all the parameters via the display and the LEDs,
- to control the fans with knobs OFF / I / II / III,
- to control the 5 external relays via knobs UP / DOWN / LIGHT / UV / GAS.
