3.2.11.
Connection to (optional) ambient thermostat
The boiler is designed to be connected to an ambient thermostat (optional, not compulsory).
Ambient thermostat contacts must be properly sized in compliance with a load of 5 mA at 24 Vdc.
Ambient thermostat cables shall be connected to electronic board pins 1 and 2 (fig. 28, 29 and 30), after having eliminated the jumper supplied as
a standard with the boiler.
The ambient thermostat cables are not to be grouped together in the same sheath as power mains supply cables.
3.2.12.
Installation and operation with (optional) Open Therm Remote Control
The boiler may be connected to an Open Therm Remote Control (non-compulsory optional accessory supplied by manufacturer).
The Remote Control must only be installed by qualified personnel.
Only use original Remote Control Units supplied by the manufacturer.
The correct operation of the Remote Control itself and of the boiler is not guaranteed if non original Remote Control units not
supplied by the manufacturer are used.
To install the Remote Control, refer to the instructions provided with the Remote Control itself.
Please note the following precautions when installing the Remote Control:
- the Remote Control wiring must not be grouped together in the same sheath as the power cables: if the cables are sheathed together,
electrical interference from other power cables may compromise the functions of the Remote Control;
- the Remote Control must be installed on an indoor wall at a height of approximately 1.5 m from the floor and in a suitable location for measuring
ambient temperature: do not install in recess or corners, behind doors or curtains, and install away from heat sources, direct sunlight, air draughts
and water sprays.
The Remote Control connector is protected against inverted polarity, and the connections may be inverted.
Do not connect the remote control to mains electrical power 230 V ~ 50 Hz.
For complete instructions on how to program the Remote Control, refer to the instruction manual included in the Remote Control kit.
Board and Remote Control communicate in each operating mode: OFF, SUMMER, WINTER, CH ONLY; boiler display layout corresponds to the setting
made from the Remote Control, as for the operating mode.
The Remote Control may be used to view and set a number of special parameters denominated TSP parameters and reserved solely for qualified
technicians (tables 14 and 15).
TPS0 parameter sets default data table and restores all factory settings, cancelling all preceding modifications on single parameters.
If a single parameter is found to be incorrect, the value given in the default value table is restored.
If the user attempts to set a value not within the permissible range for the parameter, the new value is rejected and the existing value is maintained.
