Heating mat HMT-A
This saves energy, since the heat is generated near the roots. The heat supply is continuous and
even, but not enough in most cases to prevent a sudden ambient temperature drop. A frost
monitor is in addition required to do this.
ATTENTION:
Never put a spot load on the heating mat. Also, never place heavy or sharp-edged plant pots directly
on the mat. Any ensuing damage is not covered by the warranty. The heating mat may not be folded.
Roll up the mat after use and store it in a protected place. Damages caused by kinking as a result of
folding are also not covered by the warranty.
6. How the heating mat works
If the set up is performed according to the above installation instructions, the heating mat generates a
soil temperature of up to 40 ° C. 40 ° C is, however, exceptional. Normally, soil temperatures between
12 ° C and 25 ° C are required.
Your gardener will advise you on the correct temperatures for your purpose. For instance, lettuce
seedlings require a soil temperature of max. 12 ° C, whilst tomatoes require at least 18 - 22 ° C. Since
the required temperature strongly depends on the light intensity in the area, we recommend our
SIRIUS 400 plant light for ideal seedling conditions.
The temperature (0 – 40 ° C) is set via the thermostat adjusting knob. Each division between 0 and 5
represents a temperature difference of approx. 8 ° C.
0 ≈ 0 ° C
Example:
1 ≈ 8 ° C
2 ≈ 16 ° C
3 ≈ 24 ° C
4 ≈ 32 ° C
5 ≈ 40 ° C
