10.8 ANTIBLOCKING

10.8.1 Circulating pump Antiblocking
After 24 hours of inactivity, the system circulating pumps are activated for 5 seconds.
10.8.2 Mixing Valve Antiblocking
After 24 hours of inactivity, the mixing valves must be opened for a time equal to the Mixing valve closing Time timer (TSP31) and subsequently closed for a time equal
to the Mixing valve closing Time timer (TSP31).

10.9 SENSOR CHARACTERISTICS

The temperature sensors can be controlled by a digital multimeter: disconnect the sensor from the controller and check correspondence with the following table.

10.10 USER SETTINGS

The settings for Heating, such as max. delivery temperature, external probe curve (with optional external probe connected to the boiler), weekly time programming, etc., are
independent for each zone; these are modifi ed through the Remote Control of the corresponding temperature zone. In case of direct zones, make sure to set a similar max.
delivery temperature for all the temperature zones. With Room Chronothermostats, on closing of the contact the delivery temperature will be adjusted to the max. value set
by the zone controller. The settings relevant to DHW, such as DHW temperature, Economy/Comfort mode, weekly time programming (with boiler arranged: see the relevant
documentation), etc., are managed in parallel; these are modifi ed through the Remote Controls of the temperature zones. In case of DHW weekly time programming, the
zone controller overlaps programmes coming from the single Remote Controls.

10.11 EXTERNAL PROBE/ SLIDING TEMPERATURE

The connection to the external probe must be made when it cannot be connected to the boiler board.
