Power supply
Power supply including safety switch must be installed by an authorized electrician.
The VP 18 EK -unit must be connected according to the attached electrical chart.
The unit is delivered with 1m test cable for the CTS 602 panel. The panel should be connected to
the CTS 602 control in the unit with cable type 2x2x0.25mm
2
twisted in pairs. (Maximum length
50m).
The CTS 602 panel must be placed dry and frost-
proof. The panels’ integrated feeler prevents fur-
ther cooling of the building if the primary heat-supply stops by stopping the ventilation if the panel
feeler gets below a specific value. (Factory setting is 10°C; the value can be set from 1-20°C.)
The built-in sensor of the panel prevents further cooling of the building in case of outage of the
primary heating source. Should the panel sensor detect a temperature below the set value, the
ventilation system will stop. (Factory set position is 10 °C, can be set to anything between 1 and 20
°C)
