Intermediate Heating Operation; Parallel Pump Operation; Operation Of Circulation Pump During Storage Tank Charging - Samson TROVIS 5433 Mounting And Operating Instructions

Intermediate heating operation

This function is only available in systems Anl 2 and 3. With the setting CO2 -> F10 - 1, heat-
ing operation is reactivated for 10 minutes after 20 minutes of priority (heating deactivated
during DHW heating). By setting CO2 -> F10 - 0, storage tank charging is given unlimited
priority over heating operation.

Intermediate heating
6.5 Parallel pump operation
This function is only available in Anl 2 and 3. With the setting CO2 -> F06 - 1, the circula-
tion pump UP remains switched on during DHW heating unless certain operating situations
occur. The operating situations that do not apply include those in which the actual set point
for the heating circuit is less than 40 °C or in which the Max. flow temperature would be ex-
ceeded. In these cases, the controller applies priority operation. Once a parallel pump oper-
ation cycle has been activated and the time for Stop parallel operation in case of deviation
has elapsed, system deviations greater than 5 °C cause the controller to suspend parallel op-
eration for 10 minutes and to apply priority operation.
If the Stop parallel operation in case of deviation is set to – – –, the parallel operation re-
mains active regardless of any deviations.

Operation of circulation pump during storage tank charging

This function is only available in Anl 2, 3, 4 and 6. With the setting CO2 -> F04 - 1, the cir-
culation pump continues operation according to the set schedule even during storage tank
charging. With the setting CO2 -> F04 - 0, the circulation pump is switched off as soon as
the storage tank charging pump is activated. The circulation pump returns to operate accord-
ing to schedule when the storage tank charging pump has been switched off again.
