AIR Air probe optional (*)

Alternatively, connect the wall-mounted

controller EKWHCTRL1 to the air probe

** If after switching the power on the board

detects the H2 probe, start-up occurs in normal

conditions with the minimum water temperature

when heating (30°C) and maximum when

cooling (20°C).

The board also has a function when there is no

probe, in such cases the fan stop minimum and

maximum thresholds are ignored.

Rigid or flexible wires with a 0.2 to 1.5 mm² cross-section

(0.75 mm² if two wires are connected to the same terminal

block) can be inserted in the 4 spring-loaded terminal

blocks (ref. A) for connection of the wall-mounted controller

EKWHCTRL1. If the wires have wire end ferrules with a

plastic collar, the maximum cross-section is 0.75 mm².

Strip 8 mm of the wire, then if the wire is rigid, you can

insert it easily whereas, if it is flexible, it is advisable to use

long nose pliers.

Push the wire completely in and check that it is anchored

by pulling it gently.

To disconnect the cables, press the

corresponding white indent (ref. A) with a

screwdriver and remove the conductor.
