a control board
Multi-burner unit models 399 to
1000 are configured to be driven by
one control board (named Burner 1
(Master)). On this board all external
devices are connected, such as: room
thermostat, outdoor sensor, pumps
commands, LWCO, and some internal
safety devices such as: blocked
drain magnetic switch, flue blocked
pressure switch, etc.
If Burner 1 control board fails, the
complete unit stops working. If the
installer doesn't have a replacement
part, it can replace Burner 1 control
board for another installed on the unit
and reactivate it.
To do so, operate as follows:
1.- Turn off the electrical power;

remove the cover and gain access
to the internal components;
3.- Disconnect plug "B" (plug coming
from display) from plug "A" (plug
coming from "Burner 1 (Master)");
