DHW to a higher temperature. In this direct connection to the heating system, it is necessary to keep the minimum flow through the heat pump at the level of min. 1560 l/h with sufficient heat supply for defrosting, i.e. it is necessary to have a part of the heating system without shut-off valves (e.g. thermostatic valves) installed.

If possible, we recommend not installing the heat pump in a corner or between two parallel walls because then the resulting sound pressure level may increase due to reflections from the surrounding walls. Avoid using materials with increased sound reflectivity near the device; it is unsuitable, for example, to line the surrounding surfaces with ceramic tiles. Note: dimensions are shown in millimetres.

Hoses are included in the delivery only for heat pumps supplied as a Special Offer, otherwise they must be ordered separately. Braided diffusion-tight hoses with F/F or M/F threads for RTC 20e heat pumps can be ordered in lengths of 300, 500, 700 and 1000 mm. When installing compensators and braided hoses, follow the instructions in the separate Installation Manuals that will come with these products. -

The addressing of the individual heat pumps installed in the cascade is performed via DIP switches 6, 7 and 8 on the JNP401 switch, which is located on the printed circuit board. The default address is 2. The setting options are as follows: Address Address RTC 20e - www.regulus.eu │... -
Page 16: First Start-Up And Commissioning
5. FIRST START-UP AND COMMISSIONING Commissioning must be carried out by a service provider with a valid authorization issued by REGULUS spol. s r.o. Basic steps before the first start-up: □ Before the first start up (or after a shutdown of more than 1 day), leave the unit with the power on for several hours to allow the oil in the compressor to warm up sufficiently. □ Check that the electrical installation is carried out in accordance with the applicable regulations and with the label on the unit (check in particular the size of the supply cable, values of the circuit breaker, residual current device and correct earthing). -

• Check of cover fastening. • Check of the heating water quality. • Check of the finned and plate heat exchangers for dirt As of the date of placing on the market, the RTC 20e heat pump is NOT subject to regular refrigerant leakage checks. RTC 20e - www.regulus.eu │... -
Page 18: Non-Standard Conditions And Faults
On frosty days, check for ice in unusual places (heat pump legs, condensate tray, fan, etc.). Possible causes can be: blocked condensate drain piping (e.g. when condensate freezes inside the piping), lack of refrigerant or extreme weather conditions. RTC 20e - www.regulus.eu │... -

• that no refrigerant circuit leaks are present speed at low refrigerant • technical condition of the fan and circulation pump condensation pressure • whether the expansion valve is working properly • whether the heating water temperature isn’t too low • whether the flow and return temperature difference isn’t too big RTC 20e - www.regulus.eu │... - Page 20 If the water temperature is lower than 15 °C, the compressor will switch Water temperature too low off. The compressor switches on when the flow temperature exceeds in heating or DHW mode 17 °C. This is a protection that prevents damage to the compressor. RTC 20e - www.regulus.eu │...
