12 OPERATING MODE
g
Important!!
The subjects described in this
chapter apply to each boiler module.
12.1 Operating mode (x [[)
During normal operation the code-display shows the
status (position in cycle) of the boiler module, with the
t -display indicating the actual flow temperature.
The digits or letters in the code-display have the follow-
ing meaning:
Code Description
Standby; there is no heat demand from
0

Control stop (burner off + post ventilation) :
- flow temperature T1 > setpoint + 5°
- flow temperature T1 > desired setpoint
modulating control + 5°
6
- flow temperature T1 > parameter 1
- difference flow T1 and return T2 > 10°
(factory setting); Starting condition is [
10 °.

12.2 Read-out mode (X [[)
Read-out mode is used to display various values. Press
the m key until ! appears in the code window (dot
flashes). Select the required code using the s key.
