IMPORTANT
The power supply to which the product will be connected must be protected by an
adequate residual current circuit breaker.
The type of residual current circuit breaker must be chosen by evaluating the type
of electric equipment to be used on the entire system.
With reference to the connection to the mains power supply and the safety equip-
ment (e.g. residual current circuit breaker), it must comply with standard IEC 60364-
4-41.
The power supply must comply with all regulations in the country of product instal-
lation, as well as IEE Wiring regulations.
IMPORTANT
If the power cable is damaged, please contact us on 0203 321 5929. Please do not
shorten, modify or alter the power cable or plug without authorisation from Rointe.
It will render your guarantee invalid.
8.14.1. Remote connections
The product can be connected to other remote energy systems (solar panels and solar thermal
power). The user interface has two digital inputs with the following functions:
•
Digital 1
When a dry contact is closed between terminals 30 and 31 (brown/yellow cable wires) and the
water temperature as measured by NTC1 is greater than SP8, the product stops. The product
starts again when the contact is released and the time set under C13 is reached, or immediate-
ly if the lower probe temperature is below SP8.
•
Digital 2
When a dry contact is closed between terminals 31 and 32 (green/white cable wires) and the
heat pump reaches the temperature set under SP5 (pre-set to 62ºC), the nominal hot water
temperature is increased by 7ºC. For example, if you want to increase the temperature from
62ºC to 75ºC, you can specify that by accessing parameter SP6 in the settings where there is
sufficient solar panel electrical energy. The increase in temperature from 62ºC to 75ºC should
be made using the electric heating element (if SP6 is equal to SP5, the resistor is never activat-
ed).
For connection to digital inputs, the product is provided with an additional 4-core cable that has al-
ready been linked to the circuit board of the user interface (placed inside the equipment - figure 14).
The remote links to any energy systems must be carried out by a qualified installer (junction boxes,
terminals and connection cables).
