Controllers auxiliary function:
•
Room Thermostat: The curtain is equipped with contacts to install, if desired, a room thermostat
that stops the heating temporally when reaching the programmed temperature. Its installation is specially
recommended for equipments installed in closed or small dimensions premises. In case of installing a
room thermostat remove the bridge between terminal 4 and 5, on the controller.
Remote control characteristics
Controller CH manual /automatic for warm water heated air curtains (Hand Auto) (Optional)
It permits the manual or automatic control of the air curtain. Moreover, together with the standard warm
water heated controllers functions, it includes the functions of door contact, anti-freeze sensor and room
thermostat.
Type of operating:
•
Manual: Manual selection of the fans speed (indicated with a green led). In case of installing an
anti-freeze thermostat, if the temperature decreases below the one selected, the ventilation will stop
and will feed 230Vx1 the electro valve to allow the entrance of warm water.
•
Automatic: It works automatically depending on:
o
Door contact: It allows programming the fan speed for open door. We can program the
desired speed through the buttons (indicated by orange led). When the programmed speed
is the same than the working one, the led will change into green. Through the internal
switches we can modify the time of delay (time since the door is closed till it goes back to the
normal operating).
o
Room thermostat (optional): It controls the air curtain operating depending on the selected
temperature and the Switch nº 1 (switch placed inside the controller).
Switch nº 1 – Control of the air curtain depending on the thermostat:
•
ON: The power/fan speed increases or decreases depending on the
thermostat. While the selected temperature is not reached, it will increase 1
ventilation speed every minute, till it reaches the maximum speed. When this
happens or when the temperature is over the selected one, it will decrease
one ventilation speed every minute till the ventilation stops and the electro
valve closes.
•
OFF: It connects or disconnects the minimum fan speed depending on the
thermostat. The air curtain works at speed 1 while the selected temperature
is not reached. When this reached or exceeded, the ventilation stops and
the electro valve closes. If the thermostat is not installed, switches 1 and 3
should be placed in OFF position (default position).
