In the table above, the first column represents example display

indications, in the next columns there are: parameter description, minimal

amount, maximum amount allowed to set, step of the parameter during

the setup, factory defaults, to which you can return by choosing [Prod]

option.

4.1. Pressure fan work parameters

Fan power [Π100] - this value defines power of the fan. When

"Πr"parameter is set to "0-10" this is the maximum power of the fanwhich

can be achieved during automatic fan control.

Automatic fan speed control [Πr 1] - it is on, when this parameteris set to

"0-10" and causes automatic fan speed decrease whentemperature of

water in the boiler reaches desired temperature.If this parameter is set to

"-", the fan automatic smooth speedcontrol is disabled and the fan can

work with power set by "Π" parameter. Setting parameter value in range

from 0 to 10 meanstime in minutes of the smooth fan speed increase from

40% tovalue of "Π" for smooth boiler start.

Fan work time [Πn 5] - time of turning the fan on for a while, to remove

accumulated gases. Setting the parameter to "-" turns this function off.

This function can be active in WORK mode.

Fan pause time [Πu 6] - time between fan work periods

4.2. Circulating pump parameters

Circulating pump launch temperature [P144] - temperature of water in the

boiler, which causes start of the circulating pump. Circulating pump works

independently from the control process and is launched additionally in

case of boiler overheat.

Circulating pump launch hysteresis [Ph 4] - this parameter defines what

value should temperature decrease by, below circulating pump launch

temperature, to turn the pump off.

Pause time between circulating pump 30 second work periods [Pc 2]- in

STOP mode or when room thermostat circuit is open, the circulating pump

is launched for 30 seconds, to mix water in heating circulation. This

parameter defines time between launches of the pump.

Setting the parameter to "-" turns this function off.

4.3. Boiler work temperature setting

Minimal boiler temperature [L150] - minimal temperature, which you can

set with the boiler thermostat knob.

Maximum boiler temperature [H195] - maximum temperature, which you

can set with the boiler thermostat knob.

Boiler temperature hysteresis [h 10] - this parameter defines what value

should temperature of water in the boiler decrease by, below temperature

set with the thermostat knob, to turn the pressure fan on.

4.4. Boiler overheating protection

Boiler overheating temperature [A210] - value, exceeding which causes

permanent turn off of the pressure fan and launch of the circulating pump,

to prevent boiler overheating. Overheating mode is indicated by boiler

overheating indicator and by displaying error [E 2] on the display. It can

be turned off by pressing STOP button, but only when temperature

decreases below boiler overheating temperature.

Pressure fan turning off occurs also in case of damage of the boiler

temperature sensor, which is displayed on the display by error [E 1].

STB - the controller has also additional protection from overheating, which

is independent from the processor, . In case of temperature increase over

200°F, the control process is turned off by turning the fan off and launching

the circulating pump. The fan and the pump are joined to the control

process again, when temperature reaches 190°F.

STB circuit enables more precise boiler work control and reduces

overheating possibility.

4.5. No fuel

No-fuel testing time during fuel firing start [Fd60] - after switching to

WORK mode, if water temperature doesn't reach temperature set with the

thermostat in programmed time, the control process will be turned off and

the display will show the message: [FUEL].

You can return to previous mode by pressing STOP button.

No-fuel testing time during work mode [Fb30] - in WORK mode, if

temperature of water in the boiler decreases below temperature set with

the thermostat, by hysteresis value, and don't reach temperature set with

the thermostat in programmed time, the control process will be turned off

and the display will show the message: [FUEL]. You can cancel the alarm

by pressing STOP button.

4.6. Additional output work mode [Ar 0] - the controller has

beenequippedwith a multipurpose output that can work in one of following

modes:

- mode [Ar 0] - output may control the oil or gas boiler if such boilerexists

in the heating circuit.After switching the controller on with the main power

switch theadditional boiler is turned offand it turnes on again when there is

no fuel in the solid fuel boiler.This function is useful in heating systems

where a solid fuel boiler isused to cut the heating costs. After erasing the

no fuel alarm by pressing STOP button theadditionalboiler is again turned

off and the controller works again

- mode [Ar 1] - output may control the additional alarm signaling

system.Boiler temperature sensor malfunction, overheating and no fuel

alarmswill turn on the alarm

- mode [Ar 2] - output may control the mixing valve

servo-motor.Controlling the mixing valve requires room thermostat to be

present.Mixing valve is being opened and closed depending on the room

thermostatinput. Additionally, mixing valve is opened in case of

overheating or boilertemperature sensor malfunction.

CAUTION. Equipment should be connected to additional output using

UM-1module. Connection schemes are shoun on picture 3.

4.7. Testing of device's outputs

To make checking the controller work easier, it is possible to test output

circuits which control the fan and the pump, and the circuit which controls

additional boiler. This function is available in service mode, only if the

control process is off, i.e. the controller was in STOP mode before

switching to service mode. By choosing [outP] on the display and

pressing OK button you can turn on the circulating pump for a while, by

choosing [outΠ] and pressing OK you can turn on the pressure fan and by

choosing [outr] and pressing OK you can turn the additional boiler, the

alarm signaling system or the mixing valve servo-motor on (if the

additional module is connected).

4.8. Factory defaults

You can return to standard settings, set by the producer, by choosing

[Prod] option in service mode and pressing OK button. After activating this

function, the device sets each parameter showed in the table to default.

4.9. Exiting service mode

By choosing [End ] option on the display and pressing OK button you can

quit service mode. The device also quits service mode, when no buttons

are pressed for 1 minute.

5. Additional functions

To improve comfort in heated rooms, the device is equipped with input

allowing to connect any kind of room thermostat with contact output. When

temperature in the room is below desired temperature, the circulating

pump is turned on and the room thermostat indicator is lit.

It means that the boiler should keep temperature set by the room

thermostat. After reaching desired temperature in the room, the room

thermostat indicator turns off, the circulating pump is turned off and the

boiler switches to mode, in which it's keeping minimal temperature.

CAUTION. In case of not having room thermostat in the system, the room

thermostat input contacts must be short-circuited.

6. Device failures

The controller is constantly testing if its internal circuits and temperature

sensor are working correctly. After detection of fault, it stops the pressure

fan, turns on the circulating pump and shows proper error message on the

display. In case of failure please turn off the controller, plug the circulating

pump to the power source, bypassing the controller, ensure appropriate

fuel firing in the boiler and contact the service.

When [E 1] error appears on the display, it means fault (short-circuit) in

the boiler sensor circuit or temperature below 32°F. [E 2] is displayed if

boiler overheats. [E 3] error means fault and overheating at the same

time. Appearing of [E 1] error on the display without ability to cancel it by

pressing STOP button, in spite of temperature below 190°F, may mean

permanent damage of boiler temperature sensor (e.g. if the boiler

overheated above 300°F).
