COMFORT SYSTEM facility

The COMFORT SYSTEM function built into the regulator prevents against stone deposition

between pump rotor and stator. The regulator automatically actuates the pump after the heating

season for about 30 seconds, every 14 days. Operation of the pump in this mode is signalled by

pulsation of PUMP indicator. The system begins to operate 1 minute after regulator’s switching

on. Actuation of the pump in automatic mode causes re-counting of the 14-day period from the

beginning.

Antifreeze and overheating protection system.

When the temperature decreases below 4°C regulator secures the installation against its freezing

by the pump’s turning on. Temperature’s rising to more than 90°C causes the fan’s turning off and

the pump’s turning on. The button beating alarms of the boiler’s overheating. In the case

reasons for overheating should be found, eliminated and as it follows boiler should be engaged

again by the button pressing. Pump is continuously on in case of the temperature’s

sensor breaking down.

Programming of blow-through

• Press and hold for about 3 s until the OPERATING TIME indicator switches on,

• set the blow-through time in seconds with pushbuttons

, ,

• Press

• set the blow-through interval in minutes with pushbuttons , ,

• Press .

If the temperature excess over the set one, regulator will turn the fan off from time to time.

NOTE!

- setting the blow-through time to “0” causes blow-through switching off,

- above temperature of 85°C, blow-through is switched off to prevent overheating of

the boiler.

Remote control

Regulator is accommodated for the remote „EKOSTER Control” connecting, which enables to

control and change current boiler’s temperature, preview of the pump connection and START-

STOP mode, in the same time sonic gauge alarms when the boiler’s temperature abruptly

increases to hazardous level. Remote control with 10 m wire doesn’t go as a standard set - they

are to be bought separately.

Service mode

It is for regulator’ s settings changes. To work on the mode you should:

• Swtch off the power,

• Switch the power back and in the time of some regulator’s version displaying (for example

2.2) press the button and hold it up to the moment of “HI” appearing on the screen.

Since the time screen alternately shows the symbol and value of regulation task.

With

, buttons the value can be changed and button causes moving to the next

regulation settings.
