Example of typical use of the interface/repeater unit
thermostatic control of a vELUX skylight by a
compatible thermostat
A thermostat can be used to control automatic opening
and closing of skylight(s) depending on the temperature. A
typical thermostat works by means of a dry change-over
contact that switches between two positions depending
on the ambient temperature.
The illustration shows how to connect the dry change-
over contact to the interface/repeater unit.
A thermostat set to 72°F/22°C will typically change
position (ie open the skylight(s)) when the temperature
rises above 74°F/23°C, and switch back (ie close the
skylight(s)) when the temperature has again fallen below
70°F/21°C.
The skylight(s) can be operated with the remote control
at any time.
