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. 1100 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. Approximately it is at least 5 radiators of normal size (e.g. 0.6 x 0.9 m), or at least 30 sqm of underfloor heating without the possibility to be shut off. RTC 13e - www.regulus.eu │... -

Expansion vessel 3.3. Heating system with the use of cooling RTC 13e heat pumps also allow cooling of buildings. If cooling operation is used, all tanks and chilled water distribution systems must be vapor-insulated. If there are also space heating elements in the building that are not suitable for cooling (radiators, heated towel rails, etc.), it... -

The installation may only be carried out by a person possessing a valid manufacturer‘s authorization. 4.1. Scope of supply - RTC 13e Heat Pump - Installation and Operation Manual - 2 compensators to protect the plate heat exchanger in the heat pump against frost rupture 4.2. -
Page 11: Heat Pump Placement And Minimum Distances
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. RTC 13e - www.regulus.eu │... - Page 12 – e.g. using a chemical anchor or a through-wall anchor. - Follow the instructions for the wall mounting brackets. Wall brackets (code 17458) - At the end, level the equipment with a spirit level. RTC 13e - www.regulus.eu │...

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 13e 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. -
Page 15: Electrical Wiring
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 13e - 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). -
Page 17: Maintenance, Servicing
• 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 13e heat pump is NOT subject to regular refrigerant leakage checks. RTC 13e - 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 13e - www.regulus.eu │... -
Page 19: Diagnostics And Possible Causes Of Fault Conditions
• 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 13e - 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 13e - www.regulus.eu │...
