Type 2 – Outdoor temperature compensation and sanitary water on Termo Extra or Termo Blok PTV
1. Display
temperature reading from KTY probes from – 19°C (below -19°C the display shows --)
up to +99°C (above +99°C
display is blinking),
display of the desired temperature or curve during setup.
Following warnings can be displayed:
PF – power line voltage too low or air in the boiler
P1 – frost protection for sanitary water is active
P2 – frost protection for central heating is active
o1 or c1
– thermal sensor for boiler temperature is not connected or it is short-circuited
o2 or c2
– thermal sensor for external temperature is not connected or it is short-circuited
o3 or c3
– thermal sensor for DHW temperature is not connected or it is short-circuited
when heating function is turned off, every 24 hours controller will activate circulation pump for period of 10 seconds, in
order to prevent pump bearings corrosion. That will be indicated on the display as a "running light"
12. Safety thermostat
2. Led diodes of heaters stages
The number of lighted diodes corresponds to the number of currently active heater stages (up to seven)
3. Led diode OK/air in boiler
If there is no air in the boiler, the diode lights green. If the air appears in the boiler, the diode lights red and
at the same time the operation of the device is stopped. After venting, the diode automatically changes the
color to green and the operation of the boiler is continued.
4. Led diode too low supply voltage
If the net voltage falls below 170 V red light appears and at the same time the operation of the device is
stopped.
5. Led diode indication for central heating
Indicates that the pump of central heating is active
6. Push button for adjustment of heating characteristics
7. Switch – heating on/off
8. Push-button for adjusting characteristics of sanitary water conditioning
9. Sanitary water conditioning on/off
10. Led diode indication for sanitary water conditioning,
It indicates the circulation pump operation for sanitary warm water conditioning.
11. Indicator of water pressure in heating system.
