They are reversible and can be used for heating and for cooling in summer. They can also be equipped with an optional «insulation kit» for air conditioning using fan coil units. They are composed of an outside «Inverter» unit, which is connected to the inside module by cooling connections. The inside module comes fully equipped and includes, in particular: - A DIEMATIC isystem control panel with control system that can be programmed according to the outside temperature that communicates with the outside unit and, depending on the options connected, can be used to manage a direct heating circuit, a circuit with mixing valve and one or two domestic hot water production circuits. Option of connecting heat pumps and boilers with DIEMATIC isystem control system in cascade; - Class A modulating pumps; - A hydraulic filter with isolating valve. This module is available in 2 versions: - MIT-IN/E isystem for auxiliary heating by integrated electrical resistor, which can be wired as either 2 kw single-phase, kw single-phase, or 12 kw three-phase (cannot be installed without the heat pump) - MIT-IN/H isystem for auxiliary heating by boiler.

6 THE CONTROL PANEL FITTED TO THE MIT-IN isystem THE DIEMATIC isystem CONTROL PANEL The DIEMATIC isystem control panel is a very advanced control panel, with new control ergonomics which includes electronic programmable regulation as standard to modulate the temperature in decoupling cylinder from MIT-IN by acting on the thermodynamic module and the HP circulating pump (and the auxiliary heating if in use) according to the outside temperature or according to the room temperature if a remote control is connected. As standard, DIEMATIC isystem is capable of automatically operating a central heating installation with a direct circuit without mixing valve and 1 circuit with mixing valve (the flow sensor - package AD 1 - must be ordered separately, however). By connecting another «PCB + sensor for 1 valve circuit» option AD 2), it is therefore possible to control up to 3 circuits in total and each of these circuits can be fitted with a CDI or CDR D.iSystem remote control (optional). Connection of a domestic hot water sensor makes it possible to programme and regulate a DHW circuit (package AD optional). This control system has been specifically developed to enable optimum management of systems combining various heating generators. It allows the installer to set the parameters for the entire heating installation regardless of its degree of complexity. In the context of larger installations, it is also possible to connect 2 and as many as heat pumps in cascade (or heat pumps + boilers with DIEMATIC isystem control panel). Room temperature optimisation in cooling mode is possible thanks to the installation of a remote control with room temperature sensor on an underfloor heating/cooling system (see options opposite).

If using the «internal 3-way valve kit» package HK 21, it is not necessary to order this sensor, which is included as standard in package HK 21. MCA_Q0013 PCB + sensor for 1 mixing valve - Package AD 2 This is used to control a mixing valve with an electromechanical or electrothermal motor. The PCB is inserted into the DIEMATIC isystem panel connected by pin connections. DIEMATIC isystem can receive 1 PCB + sensor option, enabling it to control 1 additional mixing valve. HA2_Q0001 Underfloor heating connection kit - Package HA 2 This cable harness is inserted into the heating pump and includes the wires for connecting a safety thermostat for underfloor heating.

In addition, they enable the self-adaptability of the heating regime for the circuit concerned (one CDI D.iSystem or CDR D.iSystem per circuit). In the case of the CDR D.iSystem, the data are transmitted by radio waves from the place where the CDR D.iSystem is installed to the transmitter/ receiver box (package AD 252) placed close to the boiler. 575Q037 Simplified remote control with room sensor - Package FM 52 This is used from the room in which it is installed to override certain instructions from the DIEMATIC isystem panel: - room temperature program and instruction override.

AD 251 AD 252 Q172A 575Q03 Radio outside temperature sensor - Package AD 251 Boiler radio module (radio transmitter) - Package AD 252 The radio outside temperature sensor can be delivered as optional equipment for systems in which the installation of the external wire connection sensor delivered with DIEMATIC isystem control panel would be too complex. If this sensor is used: - With a wire connection remote control (AD 25 or FM 52), it is necessary to order the Boiler radio module - With a radio remote control (AD 253), already combined with a boiler radio module (AD 252), control of a second module is not necessary. Condensation detector kit - Package HK Sensor measuring humidity, it has to be installed on the collector of the underfloor cooling.

PAC_Q00 EH 5 PAC_Q0021 Buffer tank B 0 T - Package EH 5 The 0 tank is use to limit operation of the compressor in short cycles and to provide a reserve for the defrosting phase on reversible Air/Water heat pumps. It is also recommended for all heat pumps connected to installations in which the water volume is less than 3 l/kw in heating output. E.g.: Heat pump output = kw Min volume in the installation: litres Dimensions of buffer tank: H 50 x L 0 x P 50 mm SIZING AIR/WATER HEAT PUMPS Air/Water heat pumps alone cannot compensate for the heat loss from a home as their output diminishes when the outside temperature falls and they shut down altogether at the so-called shutdown temperature. This temperature is -20 C (-15 C for and kw) for our range. Electric or hydraulic boiler backup is then necessary. The balance point temperature corresponds to the outside temperature at which the output of the heat pump is equal to the heat losses. Tbasis = Basis outside temperature, Teq = Balance point temperature, Tstop = Shutdown temperature For optimum sizing, we recommend observing the following rules: - 0% of heat losses m Heat pump output at To 0% of heat losses where To = Tbasis if Ts Tbasis and To = shutdown if the opposite is the case - heat pump output at Tbasis + Back-up Output = 120% of heat losses By following these sizing rules, we obtain, depending on the case, rates of cover ranging from approx. 0% to more than 0%. For more detailed calculations, you can use our DiemaPAC calculation tool available on the Pro page DiemaTOOLS: heat pump calculation, of the website: PAC_F00

12 INFORMATION REQUIRED FOR INSTALLATION HEAT PUMPS INSTALLATION - The outdoor units of heat pumps should be installed close to the house, on a terrace, on the façade or in a garden. They are designed to operate in the rain but can also be installed under cover as long as there is sufficient ventilation. There should be no obstacles to hinder the free circulation of air to the exchanger inlet and outlet (see installation diagrams below). - The emplacement of the outdoor unit should be carefully chosen and protected from prevailing winds in order for it to be compatible with environmental requirements: integration into the site, noise level. We particularly recommend: Not placing the outdoor unit close to sleeping areas Not placing it opposite a glazed wall Avoiding proximity to a terrace Moreover, we recommend positioning the unit above the average depth of snowfall in the region in which it is installed. - It is necessary to provide clearance all around the appliance to carry out connection, commissioning and maintenance operations.

Appliances must be installed, commissioned, maintained and repaired by qualified, authorised personnel, pursuant to the ELECTRICAL CONNECTION The electrical installation of heat pumps must be done in accordance with the local and national Codes of Practice and pursuant to prevailing standards, decrees and subsequent texts. The cable will be carefully chosen according to the requirements of prevailing directives, laws and regulations and in accordance with the codes of practice of the profession. following information: maximum amperage on the outdoor unit (thermodynamic unit).

Storage tank The installation of a storage tank is recommended for installations in which the water volume is less than 3 l/kw in heating output on the heat pump (remember to factor in the 0 litres in the MIT-IN isystem). It is intended: - on the one hand, to increase the water volume in an installation in order to limit the short-cycle operation of the compressor. The greater the water volume, the lower the number of start-ups of the compressor and the longer its useful life. - on the other hand, to guarantee an energy reserve for the defrosting phases.

In addition, the De Dietrich catalogue offers a commissioning service for heat pumps ; we also strongly recommend that you take out a maintenance contract. 1
