MV HEATING MV Airo 5 Rotary Control
Key
- Variable Output Button and Red Indicator Light
- Temperature Button and Amber Indicator Light
- Fan Only (Cold Air) Button and Green Indicator Light
- Control Knob
- Fixing Screw Hole – Located underneath the control knob. Use a small flat-bladed screwdriver to gently remove the knob.
The rheostat (or rotary) control works by twisting the control knob to the desired heat setting, and using the buttons listed to determine the heater’s function. The Alpine Auto model of heaters have a fully automatic altitude function that operates up to 5000m, allowing the user to take their vehicle almost anywhere!
Installing the Control
Remove the rotary knob by gently lifting it away using a small flat-bladed
screwdriver. Use the fixing screw and mounting pad provided to fix the control
to a suitable, flat, and clean surface. It is best installed so that it can be
seen and operated easily to identify working conditions and for ease of
access. Once mounted, simply push the rotary knob back into position, paying
attention to its orientation. The image below shows the control unit plug and
loom connection that it corresponds to. To fit the control into the loom,
simply push the plug in place. To remove it, push down the tab on the male
plug, and separate the two.
Variable Output Mode
In variable output mode, once turned on the heater will continue to run until it is manually turned off again. Whilst turned on, the rotary knob is used to select the power output (fan speed) of the heater. The higher the fan speed, the greater the volume of hot air will be pushed into the heating space.
- Press the top button to turn the heater on, and the red light will appear.
- Use the rotary knob to control the heaters fan speed from high to low (the higher the fan speed, the quicker the vehicle will get warmer)
- Press the top button again, to switch the unit off – The red light will switch off and the unit will then go into a two-minute cool-down cycle.
Fan Mode
In fan-only mode, once turned on the heater will only run the fresh air fan
until it is manually turned off again. Whilst turned on, the rotary knob is
used to select the fan speed. The higher the fan speed, the greater the volume
of air will be pushed into the heating space.
- Press the bottom button to use the fan-only mode. The green light will appear.
- Use the rotary knob to alter the fan speed from high to low.
- Press the bottom button again to turn the fan off, the green light will switch off and the unit will shut down.
Thermostatic Mode
In thermostatic mode, the heater will run until it has reached the set temperature and (version dependent) will either switch off completely or continue to run the fan until the temperature has dropped significantly that the heater will then relight and start again. The unit will continue to cycle until the controller is switched off completely, by pressing the thermostat button again, so the light disappears. Temperature will vary depending on where the temperature probe is installed, and how much ambient air flow it has.
- Press the middle button to turn the heater on, and the amber light will appear.
- Use the rotary knob to control the temperature from high to low. (35°C – 5°C respectively).
- Once the heater reaches the temperature set on the rotary knob, it will shut itself down.
- Once the temperature has dropped again, the heater will turn back on, and start to heat again.
- This process will continue until you press the middle button again, to switch the unit off – The amber light will switch off, and the unit will go into a two-minute cool-down cycle.
Bluetooth
To switch the controller’s Bluetooth function on turn the rotary dial down
and hold the thermostat button. When the yellow light turns on, turn the dial-
up. If both the red and yellow lights flash, Bluetooth is on. If the green
light flashes, it is off. You can now connect your phone to the controller
using the relevant smartphone app.
Fault Information
If the heater detects a fault, the controller will go into an error state. The current light (red, amber, green depending on what mode the unit is in) will switch off, and begin to flash many times, followed by a pause. To determine the fault, count the number of flashes and refer to the table below to rectify the fault.
