(according to SW8 conguration)
❷ Change-over input or output (according to SW6 conguration). If change-over output:
voltage off load < 28VDC, current < 50mA. Ensure the wires are correctly connected!
❸To connect the Bus, use the cable supplied (2x0.75², length 1 m) or twisted pair cable with
a minimum section of 6/10th, max. length. 30 m:
- 4 wires maximum per terminal
- Ensure the wires are correctly connected to the + and - poles.
- Room terminals can be connected to either one of the 2 Bus terminals.

The multizone kit offers an optional water network temperature monitoring function
(hot and cold).
This function protects the system from overheating in the water network (protection of
the slab and pipes) or from abnormally low temperature, which will generally lead to the
formation of condensation on the ooring.
This information is immediately sent to the end user via a defect fed back to
the room thermostat.
Important: this feature still requires the connection of a safety device to the system
(bimetallic strip on the circulator or condensation sensor) aimed to monitor the system's
water temperature and to cut off the water ow if necessary.
Principle for the detection of excessively hot or cold water
Depending on the entered temperature limit value (to be set at the time of installation),
the system scans the water temperature and reconciles it with the set limit value. If the
water temperature is above (if the water is too hot) or below (if the water is too cold) the
limit value after 30 minutes of circulator operation, the defect is detected and sent to the
thermostat.
If a defect is found, the circulator is shut down immediately.
The system switches the thermostat to OFF mode.
The user must then contact the installer for a diagnosis or work on the heat pump or boiler
in order to reduce the hot water ow temperature setting or feed the cold water setting
back to the system.
The system can be restarted manually from a Master thermostat or a programmer.
The water network's temperature monitoring function is reactivated.
