3.12 Installation and operation with Open Therm Remote Control (optional)
WARNING
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.
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.
To install the Remote Control, refer to the instructions provided with the Remote Control itself.
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 cables must be connected to terminals 3 and 4 of the electronic board.
The Remote Control connector is protected against inverted polarity, and the connections may be inverted.
WARNING
Do not connect the remote control to mains electrical power 230 V ~ 50 Hz.
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 the power cables may compromise the functions of the Remote Control;
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.
TSP0 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.
3.13 Installation of the (optional) external probe and sliding temperature operation
The boiler can be connected to an (optional) external temperature probe (optional, provided by the manufacturer) for sliding temperature
operation.
WARNING
Only original external temperature probes supplied by the manufacturer must be used.
If non-original external temperature probes are used, correct operation of the boiler and external probe cannot be guaranteed.
The external temperature probe must be connected by means of a double insulated wire, minimum cross-section 0.35 sq.mm.
The external probe must be connected to terminals (5) and (6) of boiler electronic board.
WARNING
The temperature probe cables must NOT be routed together with power cables.
