4. Installation and Operation
Make sure that the heating mat is disconnected from the mains before and during
installation. Fully spread out the heating mat.
Note:
Always fully unroll the mat, otherwise it may develop a fault.
Put a 2 - 5 cm thick
polystyrene board under the heating mat to reduce any heat radiation downwards.
Lay the connection lead to that it does not represent a trip hazard, or become squashed, or
come into contact with hot items.
Operation with TR-E Thermostat
To operate the Grand Top Propagator with the associated TR-E thermostat, the heating
mat and the thermostat must first be connected together. To do this, insert the mains plug
of the heating mat into the socket on the underside of the thermostat and then the mains
plug of the thermostat into the mains socket (Fig. 1).
When selecting the installation location of the thermostat, make sure that it is fully
protected from spray (e.g., condensation drip, open roof lights, etc.) and that there is no
danger of the thermostat falling into water.
You must position the sensor of the thermostat at the point where you want the desired
temperature to be obtained (e.g., directly in the plant pot compost). Make sure you do not
bend the sensor cable through an acute angle, as this may adversely affect its operation.
