CAUTION! Risk of property damage!
Risk of damage due to incorrect connection.

• Do not connect any external voltage to the terminals!

Analogue input for remote setpoint 
adjustment/manual control mode

Using the corresponding terminals in accordance with the wiring dia-
gram, remote adjustment of the setpoint or manual control mode is 
possible by means of an analogue signal (4...20 mA).

• Use a shielded cable, connect the shield at one end in the switchbox.

Setpoint changeover

Using the corresponding terminals in accordance with the wiring dia-
gram, it is possible to force a changeover from setpoint 1 to setpoint 
2 by means of a potential-free contact (normally open contact).

CAUTION! Risk of property damage!
Risk of damage due to incorrect connection.

• Do not connect any external voltage to the terminals!

External activation/deactivation

Using the corresponding terminals in accordance with the wiring dia-
gram, it is possible to connect a remote activation/deactivation by 
means of a potential-free contact (normally closed contact) after 
removing the jumper (factory-fitted).

CAUTION! Risk of property damage!
Risk of damage due to incorrect connection.

• Do not connect any external voltage to the terminals!

Frost protection (not for 

Δ

p-c)

Using the corresponding terminals (in accordance with the wiring 
diagram), it is possible to connect a frost monitor by means of a 
potential-free contact (normally closed contact).

CAUTION! Risk of property damage!
Risk of damage due to incorrect connection.

• Do not connect any external voltage to the terminals!

Protection against low water level 
(only for 

Δ

p-c)

Using the corresponding terminals (in accordance with the wiring dia-
gram), it is possible to connect a function for protection against low 
water level by means of a potential-free contact (normally closed 
contact) after removing the jumper (factory-fitted).
