Coding in the factory set condition
"With EA1 extension: DHW recirculation pump runtime for brief operation"
12:5 DHW recirculation pump runtime for
brief operation: 5 min
"With EA1 extension: Temperature demand"
1e:0 Analogue input 0-10 V:
Temperature demand from 32 to 212°F
(0 to 100°C):
1 V 50°F (10°C)
10 V
"Reset time hydraulic switch/buffer
20:... Controller integral time for low loss
header in sec, factory set condition
defaulted by the boiler coding card.
The greater the integral action time,
the more accurate but slower the
controller.
"Controller delay hydraulic switch/buffer
22:... Controller delay low loss header in
minutes, time between burner start and
controller start.
2f:0 Do not adjust!
"AM1 extension"
32:0 Without AM1 extension
"Function output A2 at AM1 extension"
