RISK OF ELECTRIC SHOCK
BOILER WITHOUT TIMER MODEL
YPLAN Wiring Guide:
The Warmhaus Minerwa boiler must have clean contact connections
and must not have voltage connected to the room stat position on our
terminal connector, therefore if the system configuration is a YPLAN you
must connect the relay supplied with our boiler as per the above image
to provide a switching method of taking mains 240v switched live supply
from the zone valve and supplying the room stat connection from the relay
output as clean contacts voltage free.
