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 accessories 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.
