EXPLAINING ZONES
One or more ice detection channels can be assigned to a zone, which then have extended control opti-
ons. When configured as a system, the 1873's ice detection channel is automatically assigned to the only
zone. The assignment of the channels to the zones within a multi channel system can be freely defined.
Zone management functions:
free assignment of an ice detection channel to one of the 4 zones, function options can be activated
−
separately for each zone
pre-heating mode with air temperature sensor for preheating all heating areas in a zone
−
−
channel coupling in order to interconnect all sensors in a zone
−
week program to automatically set the operating mode
common holiday program for all zones
−
CHANNEL COUPLING
If several ice detection channels are assigned to a zone, the channel coupling can be used to activate
an action grouping for all channels. When channel coupling is used, all heating circuits of this zone are
activated as soon as one of the combi sensors of the zone reports a temperature below the activation
temperature together with a moisture value above its moisture threshold.
If the coupling is active, the minimum heating time will be activated for all channels in a zone as soon as
moisture is detected in one of the channels.
Factory setting: No
WEEK PROGRAMS
Each zone has its own week program. In a week program a time control can be used to change the con-
trol mode of the zone automatically in a daily and weekly rhythm. A maximum of 16 switching points can
be defined for each week program.
Available control modes:
Channel: All ice detection channels in the zone operate solely on the basis of their set operating
