according to which the controller should operate. At the selected time, the
controller will enter a less efcient mode of operation, but the number of
switches will be reduced.
Power regulation
By activating the Power Control function, the main display no longer selects
the desired temperature to which we want to heat the room, but the xed
% with which the heating should work. This feature is especially useful at
the entrances to industrial buildings where the doors often open, outdoor
catering terraces, therapeutic rooms, etc.
Automatic schedule activation
If this function is active, the controller will automatically switch on
scheduled operation every day at 11:59 pm. Attention, this feature is
activated by default! If this function is activated and the heating is OFF, the
schedule will not be activated
Choice of power output
In this menu you can choose between different power output options.
Use Solid State Relay
The external Solid State Relay (SSR) DC-AC can be connected to the
controller. If SSR is connected to the controller, the feature must be
activated in the menu.
→If you do not have a Solid State Relay on the controller and you have this
feature activated, the heating will not work.
→If you have a DC-AC Solid State Relay connected to the controller and do
not activate this feature, the heating will not work.
→Using the Solid State Relay DC-AC, your IR Sun controller will operate
completely silently, and at the same time using a suitable Solid State Relay,
you can adjust even more power than 3600 W (depending of Solid State
Relay specications).
→Solid State Relay output: DC 5 V/100 mA max.
When using an external Solid State relay, IR Sun Heating Regulator also
allows you to use a relay that is integrated in the Regulator. To do this,
activate both functions: Use Solid State Relay and Use Relay function.
Bedtime
Heating Regulator The IR Sun basically uses a conventional relay for its
operation, which means that the switches are heard during operation. This
may be disturbing for some users. If you want to reduce the number of
switches, select the Bedtime feature and specify the time in which you
want to reduce the number of switches. In this menu, you can set up a
hysteresis (+ - tolerance), according to which the regulator should work.
At the selected time, the controller will go into a less effective mode of
operation, but the number of switches will be reduced. Warning: We do not
recommend extensive use of bedtime, since the outside temperatures are
the lowest in the night time, which is the time when the IR Sun heating
regualtor saves a lot of energy.
Locking the device
The IR Sun Heating Regulator allows you to lock functions with a four-
meter code. By using this function, you can completely lock the Regulator
or only partially limit access to more important functions and settings.
To lock the device, in the Advanced Settings menu you have to select the
function Lock the device and activate it. Then, you enter your preferred four-
digit password. To conrm, re enter your four-digit password. You have now
activated the device lock. In the Lock device menu, you can choose from
a variety of options:
Temperature Lock: you can specify the maximum or minimum allowed
temperature setting. Once you have dened wanted limits, the function
must still be activated.
Units/Sensor Lock: limit access to the Units/Sensor menu
Schedule Lock: limit access to schedule settings
Consumption Lock: limit access to a menu that shows the power
consumption of the electric energy
Lock all functions: to use the regulator you always have to enter a four-digit
password.
* If the device lock feature is activated, the device locks itself when the
screen turns off.
