2.57 Maximum value of heat demand signal DC
0...10 V (H1)
Adjustable temperature range for heat demand signal via input H1.
Can be matched to the voltage outputs of devices of other manufacture.
The parameter determines which temperature the maximum voltage of the setting
"Heat demand via H1" (operating line 170, setting 4) corresponds to.
This setting is active only if on operating line 170 (input H1) setting 4 "Heat demand DC
0...10 V" has been selected.
Setting range
5...130
This setting defines the temperature corresponding to 10 V of the setting "Heat demand
via H1" (operating line 170, setting 4).
Based on this temperature, the controller converts the heat demand voltage signal to a
temperature.
2.58

Operating action contact H1 and H2

The operating action of the contact can be matched to the type of output signal
delivered by a device of other manufacture.
More flexibility when using non-Landis & Staefa products (both operating actions can
be considered).
This function enables the operating action of contact H1 or H2 to be matched to the
operating action of a device of other manufacture.
Setting range
0...1
Entry:
0 The contact is a N.C. contact, which means that it is normally closed and opened
only when the third party device delivers a signal.
1 The contact is a N.O. contact, which means that it is normally open and closed
only when the third party device delivers a signal.
This setting has no impact when:
−
Input H1 is used for a heat demand signal DC 0...10 V (line 170, setting 4).
−
Input H2 is used for d.h.w. sensor 2 (B31).
