2 speed system with 2 different Fan Speed and Heating Stages (H1, H2).
•Limited heating: for safety reasons, in references OPT/RO 1000 of 9kW the heating power is limited
by the ventilation speed that we had selected, the following way:
Selected speed Max. heating power that can be selected
V1 Stage 1 heating
V2 Stage 2 heating
To apply this limitation, the default control work
jumper JP1 must be retired.
In the rest of the references, any ventilation speed
can be selected with any heating power.
Furthermore, for safety reasons of the equipment, the
heating power does not work if no speed fan is
operating. It can be selected any speed with any
heating power.
Warning: If the air ambient temperature is high, and
we select the maximum heating and the minimum
speed, the electronic safety ventilation will repetitively
activate.
•Thermostat of relay: When the equipment is stopped, and the heating has been working, there is an
increase in temperature (by thermal inertia) inside the equipment that could damage it. In order to
avoid internal damages by overheating, when we stop the curtain and the internal temperature is over
50ºC, there is a delay thermostat having the function to turn on again the fans automatically with
maximum speed till the temperature goes under 50ºC. This safety operating is indicated with a flashing
green LED.
•Safety thermostat: When the air curtain operates with heating and the internal temperature increases
over 50ºC, a safety function activates: The air curtain increases one speed every two minutes till it
reaches the maximum speed. After, it will start decreasing 1 heating stage till it stops. In case that
after 2 minutes the situation persists, the heating will block. To unblock it, we must manually reset by
disconnecting from the main supply. If in any moment the temperature decreases (below the set
temperature) this process is interrupted and everything goes back to the normal situation.
A delay in the cleaning of the inlet grille or a high ambient temperature could temporally activate this
function.
The air speed and the heating stage are indicated by a continuous lighted led, while the safety function
is indicated by a flashing LED. The blockage of the heating is indicated with the led OFF of the heating
flashing at a higher speed.
Controllers auxiliary function:
•Ambient Thermostat: The air curtain is equipped with contacts to install, if desired, an ambient
thermostat in order to stops the heating temporally when reaching the programmed temperature. This
installation is specially recommended for equipments installed in closed or small dimensions premises.
In case of installing an ambient thermostat remove the bonding jumper between terminal 4 and 5, on
the controller.
Special controllers
If there is a will to control more parameters, there are two controllers that allow a lot more possibilities in
comparison with the standard control, especially Clever. The following controllers have specific user manuals:
•Hand Auto
•Clever Control
