Picture 1. Front of the device.
Basic operation of the device is done by setting desired temperature with boiler
thermostat knob, other functions are realized according to parameters programmed in
service mode. While changing boiler temperature settings with the knob, the change is
displayed on the display for a few seconds (for example
[C 75]
) and this value means
the temperature, which the controller will be trying to achieve. This value can be
checked in temperature viewing mode. Depending on heating installation type and
service settings, additional thermostat can be used to set desired room temperature,
or desired exhaust gas temperature. Additional thermostat knob position change is
signaled for several seconds on the display e.g.:
[ 20°]
. Current value of this setting
can also be viewed in temperature viewing mode.
After pressing START button, the fan starts to work and the control process begins.
STOP button stops the fan, for example allowing to add fuel to the boiler.
If the controller isn't in service mode, the display shows water temperature of the boiler
and the last sign on the display defines mode, which controller currently is in:
for example:
[70º-]
- STOP mode
[70ºC]
- WORK mode
[70ºc]
- keeping fire in WORK mode
When the device displays boiler temperature, the function of indicator (3) depends on
function performed by additional thermostat. If the thermostat is used to set room
temperature, indicator (3) is continuously lit when room temperature is too low. If the
thermostat is used to set desired exhaust gas temperature, the indicator (3) signals
low exhaust gas temperature with quick blinking. If exhaust gas temperature is too
high, the controller turns off the fan and shows [Hot ] on the display.
4. Manual fan operation.
During boiler operation user may need to turn on the fan manually (for example, to
remove gases from the boiler before removing the fuel). Pressing START button and
holding it down for 3 seconds will turn the fan on. The fan will keep working for time set
by the service or until STOP button is pressed.
