PULSER-M
Controller with PI-control, 230...400 V AC,
wall mounting
Wall mounted electric heating controller intended for
control of radiators or electric heating coils. It is a
complete controller with built-in sensor and setpoint
adjustment. It pulses the whole load on/off and utilises
time-proportional triac control. Both automatic control
function adaptation, P- or PI-control, and supply voltage
adaptation, 230 V / 400 V.
✓ Function for minimum / maximum limitation
✓ For loads up to 3.6 kW (230 V) or 6.4 kW
(400 V)
✓ Automatic adaption of control function, P or PI-
control
✓ Supports external temperature and limitation
sensor
✓ Adjustable night set-back 0...10 K
Application
This is an electric heating controller (triac control) for
single phase or two phase electric heating. It has a built-in
temperature controller with input for an external main
sensor as well as for the sensor for minimum or maximum
limitation. It also has a built-in sensor that can be used as
main sensor for controlling room temperature.
The electric heating controller has a minimum or
maximum limitation function which is used when there is
a need to regulate the maximum or minimum supply air
temperature.
It can also provide an adjustable night set-back via an
external time switch. The setpoint is then lowered by the
set value.
Function
The controller pulses the entire output load ON/OFF. It
utilises time-proportional control, the ratio between On-
time and Off-time is varied to fit the prevailing heating
requirement e.g. On-time = 30 s and Off-time = 30 s
gives 50% output power. The cycle-time (the sum of on-
time and off-time) is fixed at approximately 60 seconds.
This control accuracy contributes to reduced energy costs
and to the increased comfort of an even temperature.
Since the current is switched by a semiconductor (triac)
there are no moving parts that can wear out. The current
is switched at zero crossing, to eliminate network
disturbance. It automatically adapts control mode to suit
the dynamics of the controlled object.
For rapid temperature changes, the electric heating
controller will work as a PI-controller with a fixed P-band
and a fixed I-time. For slow temperature changes it will
work as a P-controller with a fixed P-band.
