The "Temperature Monitor" should be secured against a wall or any vertical support:

– choose a location near the batteries and awa y from draughts which adversely affect the accuracy of temperature

measurements;

– position the unit correctly ("on" light in the top left hand corner and cable fed through from the right-hand side);

– use the holes provided in the base plate to screw the unit to the vertical support (see figure 25);

– unless the connecting cable runs on the surface, break the knock-out in the unit base plate provided for cable entry;

– secure the cable by suitable means so that it does not pull on the unit.
