The control box should be mounted within 1m of the water valves. If your greenhouse has slots for 6mm bolts, use two to fix the control box firmly to the frame. Greenhouse mounting kits are available. The control box is waterproof.
Keep it in the shade
Mount the control unit out of direct sunlight. A greenhouse or polytunnel can get very hot in the summer, and in direct sunshine, the inside of a control unit can get to more than 50 degrees C.
Circuitry inside the box will stop the battery charging when it's over 40C, which can lead to reduced watering capacity on the days when you need it most.
High temperatures will also reduce longer term battery life.
Mounting components
The WaterMate kit is supplied with a versatile mounting plate which can be used on greenhouse frames, or with screws or cable ties in a polytunnel.
