Important
The quick decrease should be switched off for the corresponding
heating circuits.
DHW thermostat: Connection of the DHW thermostat.
Limit thermostat HC: If the extension module is used for the heating
circuit, an external temperature monitor can be cut in at the inlet (e.g. for
underfloor heating).
Start prevention: With this input a burner start can be prevented.
Consumer request VK1 10V/Consumer request VK2 10V: the
application node external load x receives a voltage signal (DC 0-10 V)
as heat request. The linear curve is defined via two fix points (input
value 1/function value 1 and input value 2/function value 2).
Output request 10V: The generator receives a voltage signal (DC 0...10
V) as output request. The linear curve is defined via two fix points
(voltage value 1/function value 1 and voltage value 2 / function value 2
(only applies to H1).
Temp measurement 10V: The controller receives a voltage signal (0 - 10
V DC) as a signal for the measured temperature. The corresponding
temperature is calculated via the linear curve, which is defined via two
fixed points (input value 1/function value 1 and input value 2/function
value 2). The use of the measured temperature is defined via program
no. 5957 and 5967.

With this function, the contact can be set as a normally closed contact
(contact closed, must be opened to activate the function) or as a normally
open contact (contact opened, must be closed to activate the function).

The linear sensor curve is defined over two fixed points. The setting is
made with two parameter pairs for Funktionswert and Spannungswert
(F1 / U1 and F2 / U2).

Funct input EX21 module 1 (7342) , Funct input EX21 module
2 (7417) and Funct input EX21 module 3 (7492)
None: No function.
Limit thermostat HC: If the extension module is used for the heating
circuit, an external temperature monitor can be install in at the inlet
EX21 (e.g. for underfloor heating). If the temperature monitor is
activated: - The mixer is closed and the pump is switched off - A fault
message is issued (temperature monitor HKx) - The status "Monitor
activated is generated. If the function of the expansion module is set on
heating circuit 1-3 and the function of input EX21 for the same module is
set on the temperature monitor (HK), in this case, the status at input
EX21 is taken into consideration internally for controlling the relay
outputs (pump and mixer open/closed).
