The tekmarNet ® Thermostat 557 is a
communicating touchscreen thermostat
designed to operate either: a hydronic
radiant floor with a two stage heat pump
(water-to-air or air-to-air) for heating
& cooling and an emergency backup
heating system; or two stages of heating
and two stages of cooling. There are
three auxiliary sensor inputs that can
be used to measure room, floor, outdoor
or duct temperature. The optional floor
sensor allows precise heating of radiant
floors. Relative humidity level can be
measured and controlled using either
the built-in or external humidity sensor.
The large touchscreen display allows
you to easily adjust 7-day programmable
schedules and room temperatures to
optimize comfort and energy savings.
The 557 can connect to tekmarNet
®
controls using two or four wires or it can
operate as a stand-alone device.
