Duct Water Cooler - SystemAir SAVE VTR 100/B Betriebs- Und Wartungsanleitung

62 | Accessories
Note:
A duct temperature sensor can be connected to analog inputs 6–7 on the connection board for better
access and then configured as a supply air temperature sensor. However the internal supply air
temperature sensor must be disabled in the control panel first.
7. Water heater and its components are now configured.

Duct water cooler

A duct water cooler is supposed to be installed in supply air duct to provide a
cooled down air to the apartment.
• WC — water cooling battery
• SAT — supply air temperature sensor
• S — valve actuator
• 1 — Outdoor air
• 2 — Supply air
• 3 — Extract air
• 4 — Exhaust air

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. An 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 after water cooler. Connect the duct temperature sensor to analog input 2 (AI2) replacing the 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 and then configured as a supply air temperature sensor. However the internal supply air
temperature sensor must be disabled in the control panel first.
Configuration
1. Go to Service menu
2. Enter password (default 1111)
3. Activate the actuator. Go to Components menu, select Cooler menu and select type as Water. Choose actuator
voltage type. Do advanced settings if necessary.
