4.63 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.
1. Press the operating line selection buttons to select operating line 172.
2. Press the + / – buttons to set the required "Maximum value of the heat demand
signal".
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.
4.64 Operating action of the contact connected
to H1
•
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 selecting non-Landis & Staefa products (both operating
actions can be considered)
This function enables the operating action of contact H1 to be matched to the operating
action of a device of other manufacture.
1. Press the operating line selection buttons to select operating line 173.
2. Press the + / - buttons to select the operating action of contact H1.
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.
If input H1 is used for a heat demand signal (line 170, setting 4), this setting will have
no effect.
