C C a a u u t t i i o o n n ! ! Read and understand the instruction before using the product.
C C a a u u t t i i o o n n ! ! Ensure that the installation complies with local safety
regulations.
W W a a r r n n i i n n g g ! ! Before installation or maintenance, the power supply must first
be disconnected in order to prevent potentially lethal electric shocks! In-
stallation or maintenance of this unit should only be carried out by quali-
fied personnel. The manufacturer is not responsible for any eventual
damage or injury caused by inadequate skills during installation, or through
removal of or deactivation of any security devices.

Installation
1. Remove the front cover. The locking screw is located behind the
setpoint knob.
2. Mount the unit vertically, with the cooling flange at the top. Use
screws with a maximum head diameter of 5.5 mm. If the unit is to
be used with the internal sensor, mount it approximately 1.5 m
above floor level at a location with a representative temperature.
The air must be able to circulate freely around the unit without
disturbances from doors, furniture etc.
C C a a u u t t i i o o n n ! ! The unit emits approx. 20 W of heat which must be dissipated.
Wiring
W W a a r r n n i i n n g g ! ! The sensors have very high potential compared to neutral and
earth (230 V or more!). Thus, wiring and installation of the sensors must
comply with local codes for line voltage installations.
– Terminals 1 and 2 = Supply voltage, not polarity sensitive (Figure 1)
– Terminals 3 and 4 = Output load, resistive single- or two-phase
heater (Figure 1)
Maximum load: 3680 W at 230 V (16 A), 6400 W at 400 V (16 A)
Minimum load: 230 W at 230 V (1 A), 400 W at 400 V (1 A)
– Screw terminal: Earth connection (Figure 1)
– Terminals G and G = External sensor and setpoint, not polarity
sensitive (Figure 2 -Figure 6)
When using external setpoint and/or sensor the equivalent function
in the unit must be disabled. This is done by setting the DIP-
switches to the right of the terminal strip according to the relevant
figure.
PULSER-M
– Terminals K and K = Night set-back function (Figure 7)
Potential-free closure will give a night set-back of 0...10 K. Settable
with a potentiometer in the unit.
– Terminals M and M = Minimum/maximum limit sensor, not
polarity sensitive (Figure 8 and Figure 9)
When room control is used, there might be a need to set a minimum
or maximum limitation for supply air temperature. To use that
function, place a sensor in the supply air duct and connect it
according to the corresponding figure.
Choose function with the DIP-switches 3 and 4 according to the
figures. The switches should be in the lower position if the
minimum/maximum limit function is not used.
Set the limiting temperature on the min/max-potentiometer next to
the MM terminals. Fully counter-clockwise equals the low end
temperature of the sensor and fully clockwise equals the upper end
temperature. 3 K per division.
C C a a u u t t i i o o n n ! ! The supply voltage should be wired via an allpole switch with a
minimum contact gap of 3 mm. The cooling flange is live.
