Sending And Receiving Outdoor Temperatures - Samson TROVIS 5575 Mounting And Operating Instructions

Secondary controller:
Functions
Device bus
Send flow set point Rk1
Send flow set point Rk2
Send flow set point DHW
Send max. flow set point
Note!
The register number specifies the location where the flow set points are saved in the primary
controller. As a result, the register no. set in the secondary controller for CO7 -> F10 to F14
must be the same as the register no. adjusted under CO7 -> F15 in the primary controller.
Excessive charging temperatures in DHW circuits without control valve controlled by the pri-
mary controller are excluded when the default settings of the controller are used: while stor-
age tank charging is active, no flow temperature higher than the charging temperature is ad-
justed by the primary controller.
Nevertheless, if the Priority for external demand function is activated, the external demand
is also processed during storage tank charging.
Function
Priority for external demand

7.11.2 Sending and receiving outdoor temperatures

Controllers equipped with an outdoor sensor can be configured to supply other controllers
with the measured outdoor temperature via the device bus. This enables weather-compen-
sated control even in systems which do not have their own outdoor sensor.
