above the floor and at least 50 cm (20 in) from the adjacent wall.
Locate the unit in an area with good ventilation and an average
temperature, where it will be responsive to changes to the room
conditions. The RHT may be mounted on a flat surface.
Do not locate the RHT where it can be affected by:
• Direct sunlight
• Drafts or dead areas behind doors
• Radiant heat from appliances
• Concealed pipes or chimneys
• Outside walls or unheated / uncooled areas
2) Use the device as a template and mark the screw holes.
