Supplementary source
z
A supplementary producer can be operated in
addition to the main producer (heat pump).
Release of the supplementary producer depends
on a number of parameters a detailed description
of which is given on the following pages.
Release is effected via release relay Qx2
2-position control is effected via control relay QX3
Ux can be used to transmit the supplementary
source a DC 0...10 V signal for the required
temperature/output setpoint.
LINE
FUNCTION
3692
With DHW charging
Defines the release of the supplementary source for
DHW charging:
Locked
•
The supplementary source will not be released.
Substitute
•
The supplementary source is released only if the
main source cannot be put into operation (e.g. in the
event of fault).
Complement
•
The supplementary producer is released if the
output of the main producer is not sufficient.
Instantly
•
The supplementary source will always be released.
LINE
FUNCTION
3700
Release below outside temp
3701
Release above outside temp
Operation of the supplementary source is released
only when the composite outside temperature lies
above or below the set temperature limit.
This enables the supplementary source to lock in
a selected outside temperature range to ensure
bivalent operation of supplementary source and
heat pump.
To ensure continuous release of the supplementary
source, setting "---" must be selected on the
respective operating lines.
If both release values are enabled, the outside
temperature must satisfy both criteria, thus
ensuring release of the supplementary source.
Overtemperature protection
LINE
FUNCTION
3705
Overrun time
Overrun time of release for the external source: If
the integral indicates another heat deficit before
the overrun time has elapsed, the release remains
activated.
If the set overrun time elapses before the common
flow temperature drops below the common flow
temperature setpoint, the release is deactivated
also.
