CETA heating controller FAQ

Two types of sensors are used, which must not be swapped during connection! The connection diagram in the operating instructions must be strictly observed!

The sensors used are the PT1000, which is used as a heat supplier sensor (solar sensor), and the KVT20 or AF200.

Here are a few ohm values of the sensors:

PT1000:

0°C - 1000 Ohm

20°C – 1078 Ohm

40°C – 1155 Ohm

60°C – 1232 Ohm

80°C – 1309 Ohm

100°C – 1385 Ohm

KVT20/AF200:

0°C -  1630 Ohm

10°C – 1772 Ohm

20°C – 1922 Ohm

30°C – 2080 Ohm

40°C – 2245 Ohm

50°C – 2418 Ohm

60°C – 2598 Ohm

70°C – 2786 Ohm

80°C – 2982 Ohm

CETA 106:

The CETA 106 does not have a screed heating program, but the screed heating can be realised via the "constant control" function.

The following settings must be made:

Para 06:01 = 3 (constant control)

Para 06:04 = 2 (Heating)

Para 06:26 = to the desired fixed value.

Parameter 06:26 must be adjusted accordingly, possibly daily.

Summer deactivation only works in automatic mode.

Summer deactivation works on the long-term outdoor temperature value and not on the current outdoor temperature. The long-term value is influenced in menu 03 via parameter 03:04 (building type). Setting "1" will speed up the effect of the summer deactivation.

As a check, consider the calculated long-term value of the outdoor temperature in the info menu (menu 01 display 03:02) in order to draw information about the switching point of the summer switch-off.

1. Reduced operation" is set to "1 = AbS". (See parameter 06:06) With the setting "0 =ECO", the heating circuit switches OFF at night if the frost protection is not active or the operating mode "HEAT" has been set.

2. Frost protection is active à Possible countermeasure: Reduce the frost protection temperature parameter 06:09 to 0°C, for example. Frost protection can also be deactivated, but ATTENTION, the heating system could freeze!

3. The operating mode HEATING is set (parameter 06:04).

4. Outside sensor defective

CETA 100 | CETA 101 | CETA 103 | CETA 106:

The set minimum temperature of the heat supplier is internally supplied with a fixed switching hysteresis of 10K! If necessary, set the minimum temperature at parameter 08:05/09:05 10K lower.

In conjunction with the "ERROR" display, a numeric code is displayed specifying the error as follows:

• 11-0 = F1 interruption
• 11-1 = F1 short
• 12-0 = F2 interruption
• 12-1 = F2 short
• 13-0 = F3 interruption
• 13-1 = F3 short
• 14-0 = F4 interruption
• 14-1 = F4 short

Check the corresponding connection.

CETA 101 | CETA 102 | CETA 103:

• If DeltaT-2 is not used, parameter 09:01 must be set to "0". F4 is not connected, F2 optional.

CETA 104:

• If no active GEN (burner) is connected, the parameter 04:01 must be set to "0". F1 is not connected.
• If no heating circuit is used, set parameter 06:01 to "0". F4 is not connected.
• If no hot water circuit is used, set parameter 07:01 to "0". F2 is not connected.

CETA 106:

• If DeltaT-1 is not used, parameter 08:01 must be set to "0". F1, F3 are not connected.
  
• If no heating circuit is used, set parameter 06:01 to "0". F2, F4 are not connected.
  

CETA 100 | CETA 101 | CETA 102:

Set parameter 08:01 to "0", confirm and set parameter 08:01 back to "3".

A lock code was entered under 03:09, this is to be entered under 03:01 now.

If this code is no longer known, only a reset of the code remains. The value 911 must be set under 03:01.
