Deactivation Depending On Outdoor Temperature; Ot Deactivation Value In Rated Operation; Ot Deactivation Value In Reduced Operation - Samson TROVIS 5573 Mounting And Operating Instructions

Functions of the heating circuit
A power failure while the drying function is active or when STOP appears on the display auto-
matically leads to the drying function restarting from the beginning.
In systems in which the drying function had to be interrupted due to DHW heating (e.g.
Anl 2.1), storage tank charging does not occur while the drying function is active, provided it is
not used for frost protection of the storage tank.
NOTICE
The function block parameter can only be accessed when the function has started by deactivat-
ing the function block and activating it again.
Functions
Underfloor heating
Drying of jointless floors

Deactivation depending on outdoor temperature

5.4.1 OT deactivation value in rated operation

If the outdoor temperature exceeds the limit OT deactivation value in rated operation , the affected
heating circuit is put out of service immediately. The valve is closed and the pump is switched off
after t = 2 x valve transit time. When the outdoor temperature falls below this value (less 0.5 °C
hysteresis), heating operation is restarted immediately.
With the default settings, this means that, during the warm season, the system is switched off at
an outdoor temperature of 22 °C.

5.4.2 OT deactivation value in reduced operation

If the outdoor temperature exceeds the limit value OT deactivation value in reduced operation in
reduced operation, the affected heating circuit is put out of service immediately.
