Intrusion barrier and thermal insulator for thermostat
First Claim
1. A thermostat arrangement adapted for mounting on a wall of a controlled space, comprising:
- a thermostat having a front cover and a back plate adapted to be mounted on said wall, with the back plate and the cover defining a cavity within which are contained control circuitry, and contacts which are adapted to receive two or more thermostat wires that protrude through a penetration of said wall;
the back plate including fastener holes adapted for receiving attaching means to mount the thermostat on said wall over said penetration, and a thermostat wire opening adapted to receive said two or more thermostat wires that protrude from said penetration in said wall; and
a wall plate member adapted to be installed between said wall and the back plate of said thermostat, the wall plate member having a small wire passage aligned with said penetration and through which said thermostat wires are passed, the wall plate member, at the location of said passage, being formed of a material capable of closing over said wires, and said wall plate member serving as a barrier to direct air flowing out the penetration in said wall away from the cavity of said thermostat;
said wall plate member further including a thermal barrier to block thermal contact between the back plate of the thermostat and said wall.

Abstract
A wall plate for a wall thermostat blocks intrusion air from the thermostat. The wall plate has a wire passage aligned with the wall penetration through which the thermostat wires emerge. The wall plate member directs any intrusion air that flows out the penetration away from the cavity of said thermostat. An insulating layer, e.g., a closed-cell foam sheet, in the wall plate insulates the thermostat from direct thermal contact with the wall. The closed-cell material closes around the thermostat wires. Bosses or feet on the thermostat back plate create a standoff between the wall plate and the thermostat.

10. A thermostat arrangement adapted for mounting on a wall of a controlled space, comprising:
-
a thermostat having a front cover and a back plate adapted to be mounted on said wall, with the back plate and the cover defining a cavity within which are contained control circuitry, and contacts which are adapted to receive two or more thermostat wires that protrude through a penetration of said wall;
the back plate including openings adapted for receiving attaching means to mount the thermostat on said wall over said penetration, and a thermostat wire opening adapted to receive said two or more thermostat wires that protrude from said penetration in said wall;
an intrusion air barrier positioned at the thermostat wire opening of said back plate, having a passage through which said thermostat wires are passed, said passage closing over said wires and said barrier serving to direct air flowing out the penetration in said wall away from the cavity of said thermostat; and
a thermal barrier positioned between the thermostat back plate and said wall to block direct thermal contact between the thermostat and said wall. - View Dependent Claims (11, 12, 13, 14)
