operation manual
The Uponor Single-zone Snow Melt Control
(A3040654) is designed to operate hydronic
equipment to melt snow or ice from any
surface including driveways, walkways,
patios, business entrances, parking ramps,
loading docks, hospital entrances, helipads
or car wash bays.
The surface temperature for snow melting
is controlled automatically to reduce
operating energy costs. The control has
an automatic start and stop function when
used with the Pavement Snow and Ice
Sensor (A3040090).
Automatic start with a timed stop is
available when used with the Aerial
Snow Sensor (A3040095). The control
can operate a dedicated hydronic boiler.
Isolation relays are required to operate
line voltage pumps.
