RETURN AIR TEMPERATURE MEASUREMENT
As the default factory setting, the jumpers are configured so that return air temperature measurement is performed
via a sensor located on the RCL control module.
If the RCL control module is not sited in the air-conditioned premises or is sited at a distance for various reasons,
we recommend the use of the Return sensor (RT) located on the appliance itself. To activate the Return sensor
(RT) located on the appliance, you just have to cut off the jumper J5 located on the configuration Plug (Refer to
previous paragraph).
If the appliance is installed with an air intake duct and the fan is OFF when there is no demand for
Heating (Jumper J8 Closed) (Refer to previous paragraph), we do NOT recommend the use of the
return air sensor (RT) located on the appliance. It is preferable to install an RCL control module or
an ambient sensor box, available as options from our sales department.
POWER FAILURE
In the event of mains power supply being cut, and after power has been restored, the appliance will restart in the
same mode and with the same settings as before the power cut.
During a power cut, the RCL control module display will be maintained for a maximum period of 10 minutes.
If the power cut lasts longer than 10 minutes, the RCL control module values will be lost, but the appliance will
restart with the same operating parameters as before the power cut. After a power cut lasting more than 10 minutes,
and after restarting, the RCL values will be false.
To minimise disruptions caused by power cuts the µBMS supervision module is equipped with rechargeable batteries
offering 24 hours autonomy. After 24 hours, the time and date will need to be reprogrammed. However, the ON/
OFF programmes and the various zone parameters will remain stored in its memory.
The battery recharging cycle lasts longer than 24 hours. If another power cut occurs whilst the batteries are not
100% charged, the 24 hours autonomy cannot be guaranteed.
Theoretically, there is no need to replace the batteries. However, if they are to be replaced, we recommend using
the same type of batteries as those originally fitted. The old batteries should be disposed of in a recyclable container
intended for this purpose.
REMOTE ON/OFF MAKE/BREAK SWITCH
An make/break switch can be connected to the CLOCK input on the STORM PCB for Remote control of the ON/
OFF modes.
J3 Closed = ON / OFF with restarting via the RCL possible (CLOSED factory setting)
Open = Remote ON /OFF closed = OFF Mode
Operating principle dependent on J3 statuses and CLOCK input
J3=>open
If CLOCK = Closed, then OFF Mode and no command possible via the RCL. In this event, CLOCK input
has priority.
If CLOCK = Open, then ON Mode.
Switching CLOCK input from the Closed position to the Open position results in ON Mode, irrespective of the
Mode prior to switching.
J3=>Closed
This configuration provides the same level of priority between the CLOCK input and the RCL:
If CLOCK = Closed => then ON Mode
If CLOCK = Open => then OFF Mode
Switching CLOCK input from the Open position to the Closed position results in ON Mode, irrespective of the
Mode prior to switching.
General remarks:
A separate make/break switch must be used for each machine.
We recommend the use of wire with a maximum section of 1 mm².

- An outdoor air intake new air may be required for ventilation the blown air temperature must be controlled in order to avoid the temperature of the mixture of outdoor air and return air at the heat pump inlet exceeding the appliance s operating limits it is also common practice to shut down ventilation during periods of inoccupation night time setting of the set temperature 12
- And release a small length 12
- Each appliance s ventilation system is generally a sub system within the building with its own distribution duct network the simple introduction of outdoor air into each return air plenum quite close to the unit s return air intake is sufficient and recommended new air should not be introduced directly into the appliance provide for a sufficient distance to ensure effective mixing of the outdoor air with the return air refer to operating limits 12
- Each unit is supplied with a connection frame also serving as the filter support this enables to filter to be removed from the side without having to dismantle the duct or the connection frame 12

- The flow static pressure adjustment is made with the aid of a variable pulley when adjusting this pulley it is important to ensure that the belt is positioned properly the pulleys belt assembly must be aligned perfectly and the belt tensioned in accordance with best practices 12
- The unit sizes 096 to 120 can be supplied configured for either frontal air blowing known as in line or for side air blowing known as rear it is also possible to modify the air blowing configuration on site to achieve this 12

- Initially closed the valve opens 30 seconds before the compressor starts and closes 20 seconds after it stops 27
- Motorised water valve 27
- Operate the air conditioner in the presence of the user and explain all functions 27
- Place the plugs back on the valves and check that they are properly tightened 27
- Show him how to remove clean and place back the filters 27
- The ofan output marked 6 on the storm pcb can be used for a 230 v connection to supply a motorised water valve the valve motor capacity must not exceed 250 watts 27
- When a high or low temperature limit alarm code is activated the compressor stops and the motorised valve closes after 30 minutes the valve re opens for 1 minute to allow for water outlet temperature measurement this operation will be repeated every 30 minutes until the water outlet temperature measurement authorises at logic level the compressor to restart 27
- When this valve is installed on the system it limits main circulation pump energy consumption as well as limiting the overall pressure losses in the hydraulic circuit 27
