Aircirculation Heater Phoenix 2.8
Winter operation:
Step 1: Select the desired operating mode on selector switches 1 and 2.
Depending on size and location of the greenhouse, a heating power setting of 2 800 W
or 1 800 W is recommended in the winter months. In autumn and spring, however, the
lower setting of 1 000 W will often suffice.
1 800 Watt: Ideal frost protection for a greenhouse up to approx. 3 x 4 m.
2 800 Watt: Ideal frost protection for a greenhouse up to approx. 3 x 6 m.
Note: Should you have sensitive plants (e.g. cacti) that cannot tolerate temperature
variations in your greenhouse during winter, we recommend operating the heater in
operating mode 3b, 4b or 5b. In these operating modes, the air is continuously
circulated and evenly distributed, avoiding large temperature gradients between upper
and lower layers of air.
The same applies to greenhouses with very high humidity. The danger of fungi and
mould is averted through continuous air circulation.
Operating modes 3a, 4a or 5a are appropriate if it is merely necessary to protect more
robust plants against frost. If in doubt, please consult a gardener about this.
Step 2: Set the desired temperature on the thermostat dial.
Referring to the above example, determine the thermostat setting corresponding to the
desired temperature and set the thermostat. Now allow the heater to run for a while and
monitor the temperature using a thermometer (we recommend a MIN-MAX
thermometer). Make minor adjustments up or down if the desired temperature is not
maintained.
This setting only needs to be made once, during initial start-up. After the correct setting
has been made, the heater will keep the greenhouse temperature constant.
Note: It is unfortunately not possible to show temperatures on the dial of the thermostat
because the temperature is dependent on size, insulation, stocking and location of each
individual greenhouse.
Summer operation:
Select operation with air circulation to ventilate your greenhouse in summer or promote plant
pollination. Turn the selector switches to position 2 and the thermostat to level 10 for this purpose.
Recommendation:
Should you wish to keep valuable plants in your greenhouse over winter, we recommend installing a
second source of heating as a backup if this heater should fail (e.g. power failure). In this way you can
prevent your plants from succumbing to frost.
Note: Some smoke or smell may be evident during initial start-up. No need for concern. This is
produced by residues of oil or dust on the heater elements due to the manufacturing process.
Safety feature
Temperature-controlled switch-off: The apparatus will automatically switch off temporarily if it
should overheat. To restart, switch off the heater for 5 to 10 minutes to cool down. Another reason for
automatic switch-off may be blockages in the air inlet or exhaust apertures. In this case, please
remove the obstructing objects.
It may, however, also be an indication that the fan has failed. In this case, switch off the heating
apparatus, unplug it and call on an authorised technician for repairs.
