Functions of the heating circuit
In systems in which the drying function had to be interrupted due to DHW heating (e.g. sys-
tem Anl 2.1, see section 5), storage tank charging does not occur while the drying function is
active, provided it is not used for frost protection of the storage tank.
The function block parameters can only be accessed after after starting the function by deac
-
tivating and activating the function block again.

6.4 Deactivation depending on outdoor temperature
6.4.1 OT deactivation value in rated operation
The associated heating circuit is immediately switched off when the outdoor temperature ex-
ceeds the limit 'OT deactivation value in rated operation'. The valve is closed and the pump
is switched off after t = 2 x Valve transit time. The heating is immediately switched on again
when the outdoor temperature falls below the limit (minus 0.5 °C hysteresis).
The default setting causes the system to be switched off during warm weather at an outdoor
temperature of 22 °C.

6.4.2 OT deactivation value in reduced operation
The associated heating circuit is immediately switched off when the outdoor temperature ex-
ceeds the limit 'OT deactivation value in reduced operation'. The valve is closed and the
pump is switched off after t = 2 x Valve transit time. The heating is immediately switched on
again when the outdoor temperature falls below the limit (minus 0.5 °C hysteresis).
