Electrical installation and service must be car-
ried out under the supervision of a qualified
electrician. Electrical installation and wiring

Sensors
VPD can be supplemented with up to two hot water
sensors, one for display and one for control. The display
sensor is positioned in the submerged tube for the
display sensor (UA1) and the control sensor in the
submerged tube for control sensor (UA2). In cases
where it is only possible to connect one sensor, use the

of the heat source.
