For those seeking a simple, accurate and cost effective method of

maintaining desired comfort temperatures in premises equipped

with fan-coil units or with chilled beam ceilings and radiator heating

systems, the Danfoss range of On/Off and 0-10v proportional

electronic room controls is the answer. This range includes models

ideally suited to 4-pipe or 2-pipe heating/cooling systems including

fan-coil units, split packaged systems and chilled ceiling systems as

well as traditional radiator based heating systems.

Using advanced chrono-proportional control the RET range of

on/off thermostats provides accurate energy efficient control of

heating systems whilst maintaining traditional use of on/off control

for cooling modes if required. As the name suggests, chrono-

proportional control is based upon regulating the amount of time for

which the valve opens instead of the temperature-event based On/

Off cycling of a traditional room thermostat. In operation, each hour

is split into sections (either 3 or 6) and the controller calculates the

proportion of these periods for which the valve opens to maintain

desired comfort level.

The REP range of 24Vac/dc electronic controls allow for 0-10v

proportional control with or without selectable fan speeds. Use

of 0-10V control thermostats paired with an appropriate Danfoss

actuator and valve allow for highly accurate valve positioning with

the output voltage from the thermostat to the actuator proportional

to the room temperature deviation from setpoint. This allows a high

level of control ensuring optimal comfort conditions.

Through the introduction of the RET and REP room thermostats,

Danfoss aims to show that improved system efficiency can be obtained

without compromise on comfort and in fact improved comfort

and improved system efficiency can be provided simultaneously

if advanced controllers running chrono-proportional or 0-10V

proportional control are used in combination with complimentary

valves and actuators.
