boiler has an IPX5D protection level. Power supply cable should be connected
to 230 V +%10; -%15 50Hz grid with L-N poles and relying on the earth
connection, high voltage category 3rd class multiple poled disconnected should
be envisaged on the same grid. Contact our Authorized Warmhaus Service for
replacement of the cable.
The power supply cable must follow the specified route. In case of
replacing fuses on the board, use 2A or 3,15A quick type fuse.
In order to feed the device from the mains, adapter, multiple
sockets and extension cables are not permitted.
2.4.3. Optional Controls: Room Thermostat, Outside Temperature
Sensor, Connections and Installation
Room thermostat, Outside Sensor, etc. control devices must be connected
to Warmhaus boiler devices by the authorized service personnel; In case
connections are performed by unauthorized persons, boiler warranty shall
be void.
Room thermostat, outside Temperature Sensor, etc. control
devices are provided as optional accessories for Warmhaus boiler
devices and they must be Warmhaus approved.
Please follow instructions of use for placement of outside Temperature
Sensor.
This sensor can be directly connected to electrical installation of the boiler,
and it automatically reduces the maximum return water temperature in
the installation when outside temperature rises for enabling functioning
according to outside temperature changes sent to radiator installation
outside Temperature Sensor is activated when connected as independent
from the used room thermostat typology and functions together with
room thermostats. The relation between installation input temperature and
outside temperature is defined according to curves in the diagram from
position of the button located on the panel of boiler (or on the control panel
if connected to boiler (Figure 29).
Electrical connection of the Outside weather temperature Sensor shall be
made to the terminals to which the White & White cables of the Aux cable
connected to the electronic card of the boiler are connected (Figure 28).
