Installation and connection
1. Install a duct water cooler in the duct. Connect pipes, 2/3–way valve and actuator.
Important
Do NOT use 24V DC power output from the connection board for valve actuator.
2. Connect actuator (S) to any free analog output.
3. Internal supply air temperature sensor (SAT, default connection AI2 on the main circuit board) must be replaced by a
duct temperature sensor which can be acquired as an accessory. A duct temperature sensor must be installed in the
duct before water heater: Connect duct temperature sensor in a place of internal supply air temperature sensor.
Note:
A duct temperature sensor can be connected to analog inputs 6–7 on the connection board for better
access when the internal supply air temperature sensor is disabled in the control panel.
