4.6 Tmax pool/Tmax pool HE

Heat exchanger probe deactivation temperature. If this value is exceeded in the specified sen-
sor, the controller deactivates the pump or associated valve. If this value on the sensor is less
and the other conditions are met, the controller will activate the pump or valve.
Temperature values set too high can cause overheating or damage to the system.
Overheating protection must be the user's responsibility!

4.7 Temperature priority

Temperature level for load with absolute priority. In systems with two storage tanks, the storage
load with lower priority occurs only after the temperature limit set on the storage sensor with
higher priority has been exceeded.

4.8 Loading time

Load interruption in storage with lower priority. The storage load with lower priority is interrupted
after a certain settable time, to check if the collector has reached the temperature level neces-
sary to start loading the storage with lower priority. If so, the priority storage is loaded. If not, the
increase is measured (see "4.9 Increase" on page 156), to check if it is possible to load the
priority storage in a short time.

4.9 Increase

Load pause lengthening due to temperature increase.. To allow accurate setting of load pri-
orities of multi-storage systems, in this menu it is necessary to set the temperature increase
of the collector so that the interruption of storage loading with lower priority is prolonged by
one minute. The interruption is prolonged because it is expected that the increase in collector
temperature can quickly load the storage with higher priority. As soon as the Δt conditions are
reached, the priority storage is loaded.
f the temperature increase is lower than the set value, the storage load or storage with lower
priority will be activated again.
