Relay status RO/RC – special setting for status ‘Heating On’
Heating On
is a logical status for systems with temperature sensor . It means that real
sensor temperature is below set up level and controller should provide a special signal to
the system – either close or open relay contacts .
Heating On
is a logical status that corresponds to heating system type . And some heating
systems, for example electrical, mostly need relay that closes contacts when the heating
is on . But another heating systems, for example water based, sometimes need relay that
opens contacts when the heating is on . For this purpose,
DEVIreg™ Multi
has possibility
to set up relay status for heating – ‘open’ or ‘close’ .
Additionally, this relay status allows to implement both heating and cooling control, because
cooling is system having opposite algorithm to heating system .
The special setting for logical status
Heating On
is named
Relay status RO/RC
– Relay
Opened (
RO
) or Relay Closed (
RC
) each Channel Relay can be separately set up to status .
Factory setting –
RC
for relays or relays contacts which are normally opened (
NO)
.
NB: This setting mostly works only when controller is powered!
Setting
Relay status RO/RC
can be done by the following menu sequence:
EN:
Main Screen – Enter to Main Menu – Channels settings – Channel #X –
Relay status RO/RC – { Enter – Up/Down (RO/RC) – Enter }
EN: Main Screen – Enter to Main Menu – Channels settings – Channel #X – Relay
status RO/RC – { Enter – Up/Down (RO/RC) – Enter }

1S or Single Sensor mode and Sensor Type set up
4.4.3.1 1S mode
Single sensor control (
1S
) is mode with one temperature sensor .
And can be individually set up for any Channel .
The mode logic algorithm is the following: if sensor temperature is below set up value
then heating is turned on, and if sensor temperature is above set up value then heating is
turned off .
