General Introduction - Immergas MAGIS M4-30 Use And Installation

2

GENERAL INTRODUCTION.

• Magis M4-30 block heat pumps are used both for heating and cooling applications and for domestic hot water tanks.
They can be coupled with fan coils, floor heating applications, low-temperature high-efficiency radiators, domestic hot
water tanks and solar kits.
• The unit is supplied with a control panel.
NOTE
- The maximum length of the wiring that guarantees communication between the heat pump and the control panel is
50 m.
- The power cables and communication wires are laid separately and cannot be placed in the same duct. Otherwise there
would be electromagnetic interference. The power cables and wires for communication must not come into contact
with the refrigerant pipe which at high temperatures could damage the wires.
- The communication wires must be in shielded lines, including the line that goes from the heat pump to the control
panel.
1) Heat pump capacity.
2) Required heating capacity (depending on site).
3) Additional heating capacity supplied by a backup heater.
Domestic hot water tank (optional)
A domestic hot water storage tank can be connected to the unit (with or without tank booster heater (TBH)
The tank booster heater (TBH) must be installed below the temperature probe (T5)
The heat exchanger (coil) must be installed below the temperature probe.
Room thermostat (optional)
The room thermostat can be connected to the unit (the room thermostat must be far away from the heating source when
the installation place is chosen).
Solar kit (optional)
A solar kit can be connected to the appliance for the domestic hot water tank.
The unit has a freezing prevention function using the heat pump to keep the water system safe from freezing in all condi-
tions. Since a power failure could occur while the unit is unattended, it is recommended to empty the system (if there is no
glycol in the water). (Chap. 9.4.4 Anti-freeze protection of water circuit).
