Selector switch:
Step 1: Select the desired operating
mode on selector switches 1 and 2.
Depending on the size and location
of the greenhouse we recommend
selecting a heating performance of
2800 watts or 1800 watts in the winter
months. On the other hand, the low-
er performance of 1000 watts is often
sucient in the transition periods
(autumn and spring).
1800 watts: Ideal frost protection up
to a greenhouse size of approximately
136 sq.ft. (12 m²). 2800 watts: Ideal
frost protection up to a greenhouse
size of approximately 216 sq.ft. (20 m²).
Note: If you have sensitive plants in
your greenhouse over the winter (e.g.
cacti) that cannot tolerate fluctuating
temperatures then we recommend
