5.3.11 Release input
The boiler has a release input (normally open contact). This input relates
to the RL terminals of the connection terminal block.
If this contact is closed when there is a heat demand, the boiler will be
blocked after a waiting time.
Change the waiting time of the input by configuring the AP008 parameter.
Important
Only suitable for potential-free contacts.
5.3.12 Connecting external sensors
Tdhw Tank sensor (NTC 10 k Ohm)
Tflow Boiler flow temperature sensor (NTC 10 k Ohm)
Tout Outdoor temperature sensor (NTC 10 k Ohm)
The sensor connection contacts are dry contacts.
5.3.13 Connecting a tank sensor or thermostat
A sensor or thermostat can be connected to the Tdhw terminals of the
connector.
1. Connect the domestic hot water sensor or the tank thermostat to the
Tdhw connector.
