3.1 Controller Settings Description
If boiler temperature is lower than «
Unit Switch Off Temperature»
,
it means that the
Controller is in «
Standby»
,
mode in which all the loads are deactivated. If boiler temperature
is higher than «
Unit Switch Off Temperature»
, it means that the Controller is in
«
Operation
», mode in which the blow-off (fan) operates on a continuous basis. Operation
time for fuel supply gear is set up by the consumer manually (the consumer set up both
operation time and interval time for fuel supply gear). If boiler temperature is equal or higher
than the preset temperature, the Controller is in «
Standby»
mode
.
Each Controller shall be adjusted individually depending on the type of fuel used, and
boiler model.
The manufacturer is not responsible for consequences of improper setting up of the
Controller.
The Controller controls the fan with constant running capacity that is set up in the
User Menu with increments of 5% in the range of 0% to 100%. Once the preset boiler
temperature is achieved the Controller switches off the fan (moves to «
Standby»
mode). If
boiler temperature drops lower than the preset temperature up to the boiler hysteresis value
AIR BIO renews the fan operation (back to operation mode). When controlling the fan
operation in «
Standby
» mode, the Controller carries out periodic «
Blow Off
» of the boiler.
Operation duration and intervals for switching on the boiler blow off function are set
up in the User Menu.
Once the boiler reached «
Pump Switch On Temperature
»
, the Controller switches on
the central heating pump. If boiler temperature drops lower than «
Pump Switch On
Temperature»
minus
«
Pump Hysteresis
»
, the Controller switches off the central heating
pump.
