HRC70 How to unlock and lock the keypad ? ```

Question 1

Can you heat a swimming pool with an HRC70 heat pump ?

Accepted Answer

Yes, the HRC heat pump can heat a swimming pool via its heating circuit No. 1.
The pool must have its own water filtration/recirculation system with a heat exchanger. A pool sensor (ref. 710029) needs to be added to activate the function and control the temperature.
If you want to alternate between heating in winter and pool heating in summer on the same zone 1, a "summer pool control" kit (ref. 751006) allows for easy switching between functions.

Question 2

Producing domestic hot water with a HRC heat pump.

Accepted Answer

For optimal performance, we recommend autonomous domestic hot water production with a thermodynamic water heater. A separate solution (dedicated HRC for heating and dedicated thermodynamic water heater for hot water) offers much better performance than dual-service systems on the market.

Domestic hot water production by the HRC heat pump is also possible if the heating circuit is a high-temperature circuit (radiators).
To do this, the following accessories need to be added:
- Preparing tank with oversized heat exchanger specially designed for heat pumps (300 liters ref. 351000)
- Second direct circuit kit (ref. 751003)
- Sanitary probe (ref. 710029)
- Directional 3-way valve 1" (ref. 710098)

If the heating circuit is a low-temperature circuit (underfloor heating), this is not possible, and a single-circuit underfloor heating kit with a 3-way valve must be added (ref. 411002).

Question 3

Powering 2 independent circuits with an HRC heat pump

Accepted Answer

Depending on the nature of the 2nd circuit, add the appropriate kit:
- Direct circuit / radiators: 2nd direct circuit kit (ref. 751003)
- Mixed circuit / floor: 2nd circuit kit with 3-way valve (ref. 751007)

Question 4

Can a radiator circuit be supplied with an HRC70 heat pump ?

Accepted Answer

Yes, this is the default configuration of the heat pump from the factory.
The HRC comes standard with an outdoor sensor. Its connection to the HRC hydraulic controller is mandatory and allows for the automatic adjustment of radiator temperatures based on outdoor conditions.

Question 5

Should an electric backup be planned ?

Accepted Answer

No, the HRC heat pump already has a 6 kW electric backup which can be activated through simple configuration.
In case this electric backup is insufficient, the HRC controller includes the necessary hydraulic connections and control for connecting an electric boiler as backup.
The heat pump always takes priority, and the electric backup is only activated if necessary (in case of low outside temperatures or insufficient power).

Question 6

Keeping your existing oil boiler with the HRC heat pump

Accepted Answer

Yes, the HRC heat pump can operate with a backup from an oil boiler. The HRC controller includes the necessary hydraulic connections for its connection and control of the oil boiler as a backup.
The heat pump always takes priority, and the backup is only activated when needed (in case of low outside temperatures or insufficient power).

Question 7

Where can I find the serial number of the HRC pilot ?

Accepted Answer

The serial number of the HRC pilot is indicated on the nameplate, located inside the pilot on the electrical box.
The serial number consists of 9 digits. We recommend you to write it down and provide it during your exchanges with our technical services.

Question 8

Where can I find the serial number of the HRC heat pump ?

Accepted Answer

The serial number of the HRC heat pump is located on the nameplate, which is situated on the side of the electrical box.
The serial number consists of 9 digits. We recommend noting it down and providing it during your interactions with our technical support services.
