CONNECTING THE CLIMATE SYSTEM
A climate system is a system that regulates indoor
comfort with the help of the control system in F730 and
for example radiators, under floor heating/cooling, fan
coils etc.
• When connecting to a system with thermostats on all
radiators, a relief valve must be fitted, or some of the
thermostats must be removed to ensure sufficient
flow.
