Installation Manual 13
If is installed with pre-existing boiler, the boiler and THERMA V should not be
operated together. If entering water temperature of is above 55°C, the system will
stop operation to prevent mechanical damage of the product. For detailed electric wiring and water
piping, please contact authorized installer.
Some installation scenes are presented for example. As these scenes are conceptual figures,
installer should optimize the installation scene according to the installation conditions.

Typical Installation Example
Note:
• Room thermostat
- Type of thermostat and specification should be complied with chapter 4 and chapter 7 of
installation manual.
• 2way valve
- It is important to install 2way valve to prevent dew condensation on the floor and radiator while
cooling mode.
- Type of 2way control valve and specification should be complied with chapter 4 and chapter 7 of
installation manual.
- 2way valve should be installed at the supply side of the collector.
• By-pass valve
- To secure enough water flow rate, by-pass valve should be installed at the collector.
- By-pass valve should guarantee minimum water flow rate in any case. Minimum water flow rate is
described in water pump characteristics curve.
CASE 2:
Connecting Sanitary Water Tank

Note:
• Sanitary water tank
- It should be equipped with internal electric heater to generate sufficient heat energy in very cold
season.
• 3way valve
- Type of 3way valve and specification should be complied with chapter 4 and chapter 7 of
installation manual.
