YKlon control board
The equipment is controlled by means of a resident software
in the main board. This system operates in accordance with
the position of the microswitches on the main board. The
control algorithm also varies in accordance with the acces-
sories detected by the board and installed on the unit.
Failures are indicated by the red LED of the board (V3) by
means of communications with the DPC 1 thermostat and
the activation of the K5 relay with the output of the 24 VAC
R phase at terminal AL of connector J2.
For further information please see the Technical Information
of the YKlon control board.
