6.7. Boiler burnout detection
6.7.1. No fuel
If during automatic operation the boiler outlet water temperature remains below the F0 setting for a
period of time set in the F09 setting, then the Controller considers the boiler as “burned out” and enters the
AL13 alarm condition.
6.7.2. Sudden Drop of Outlet Water Temperature
If during automatic operation the boiler outlet water temperature drops by 10°C, and during that
dropping period the temperature does not rise by 4°C, then the CH pump is switched off, and the Controller
goes into the burnout detection mode.
The Controller waits for the period of time set in the F10 setting, during which it checks whether a rise
of 4°C occurs. If YES, then the burnout detection condition is stopped, and the CH pump (if necessary) is
started. If NOT, this means that the furnace is burned out – the Controller enters the AL13 alarm condition.

. TEMPERATURE LIMITER (STB)
The GH10PD Controller can be equipped with an additional independent temperature limiter STB via
terminals 1 and 16.
WHEN THE TEMPERATURE LIMITER IS NOT USED, TERMINALS 15
AND 16 SHOULD BE SHORTED.
If due to boiler temperature rise the temperature limiter is activated and opens its terminals, it will disable
feeder and fan power supply in order to stop fuel and air delivery do the boiler. After approximately s from
limiter activation the Controller indicates the AL1 alarm.
Return to normal boiler operation is possible when the boiler temperature drops to a level enabling limiter
reset (temperature level depends on the limiter model used).
For safety reasons the Controller does not resume automatic operation on its own.
For the Controller to resume operation you have to, after resetting the limiter, press twice:
– pressing for the first time cancels the alarm and disables the Controller,
– pressing for the second time reactivates the Controller,
– pressing causes the Controller to switch to automatic operation mode.
CAPILLARY TUBE PUNCTURE OR BREAKAGE INDICATES THAT
TEMPERATURE LIMITER FILLED WITH LIQUID LEAKS, WHICH RESULTS IN
ABNORMAL OPERATION OF THE GH10PD CONTROLLER.
IN CASE IF THE ABOVE-MENTIONED DEFECT IS FOUND, IT WILL BE
NECESSARY TO DISCONNECT TEMPERATURE LIMITER FROM THE
GH10PD CONTROLLER, REMOVE IT AND REPLACE WITH A NEW DEVICE.
9. ROOM THERMOSTAT
The GH10PD controller can cooperate with external room thermostat ( Fig.1), which can put coal
boiler in blockade position when temperature is reached in room.
During blockade position C.H. pump stay off after 4 minutes, for the moment when temperature in room is
reached (short circuit contact). The boiler start working in maintain operation mode.
The controller GH10TA passing from automatic operation to maintain operation mode just from time
to time, when the boiler temperature is higher than minimum temperature adjust in F03 service parameter.
When room thermostat put controller in blockade position, the boiler is in maintain operation mode and boiler
temperature fall down less than F03 service parameter than the controller come back to automatic operation
mode until both conditions will be accomplish.
The controller supports the room panel of our manufacture. The controller responses to the panel orders
if the controller is under the automatic operation mode. Where the malfunction occurs to the connection with
the panel, the controller will resume the operation with the user programmed settings.
The illuminated dot
on the segment on the left-hand side of the display shows that the communication link is operable.
