sensors of the main controller.
10. Valve removal
This function is used for a complete removal of the valve from the
controller memory.
Valve removal
is used e.g. at disassembling the valve or
module replacement (re-registration of a new module is necessary).
IV.p) Valve 2
If the user wants to control the second optional valve, they should, like
in the previous case, register valve 2 (additional) and configure adequately all
settings in the same manner as in the case of valve 1.
IV.r) Communication mode
The user may set the communication mode as
main
(independent) or
subordinate
(in cooperation with the with primary controller mounted on the
boiler). If the communication mode is selected as
subordinate
, the valve
controller operates as a module and all its settings are made from the boiler
controller.
IV.s) Weather-based control
By means of this parameter, it is possible to adjust the set valve
temperature for relevant values of external temperatures. On the basis of
agreed points, values for intermediate points are calculated.

Heating curve –
it is a curve, according to which the set controller
temperature is determined, on the basis of external temperature
.
In our
controller, this curve, is constructed on the basis of four points of set
temperatures for respective values of external temperatures. Set
temperatures must be determined for external temperatures - 20ºC, - 10ºC,
