SPACE HEATING WITH AN AUXILIARY BOILER
1. Space heating application by either the Daikin
Altherma
TM
Hydrobox or by an auxiliary boiler
connected in the system.
2. An auxiliary contact decides whether the Hydrobox or
the boiler will operate.
3. The auxiliary contact can be an outdoor temperature
thermostat, an electricity tariff contact, a manually
operated contact, etc...
4. Domestic hot water in such an application is always
produced by the system tank connected to the
Hydrobox, including when the boiler is in operation for
space heating.
