Thermostat with limited adjustment restraining guard

A locking device for a thermostat of the type comprising (i) a thermostat housing adapted to be secured to a mounting surface;

• (ii) an adjustable thermostat device contained within said housing;
• (iii) a user adjustment control associated with said thermostat housing, said user adjustment control being coupled to said adjustable thermostat device to adjust first parameters for the operation of said adjustable thermostat device;
• (iv) a securable adjustment control associated with said thermostat housing, said securable adjustment control being coupled to said adjustable thermostat device to adjust second parameters for the operation of said adjustable thermostat device;
• (v) a cover member movably mounted with respect to said thermostat housing, said cover member moving between a first position where said securable adjustment control is covered by said cover member and a second position where said securable adjustment control is exposed to allow adjustment of the same by a person, said user adjustment control being exposed to allow adjustment in said first and second positions;
• (vi) a catch surface defined by said thermostat housing and/or said cover member, when said cover member is in said first position;
• and (vii) a second mating locking surface secured to said thermostat housing base, said second mating locking surface mating with said first mating locking surface, and said locking device comprising:
• (a) a movement restraining member dimensioned and configured in a locking position to engage said catch surface and overly at least a portion of said cover member when said cover member is in said first position, said movement restraining member being configured and dimensioned to prevent movement of said cover member from said first position to said second position when said movement restraining member is in said locking position overlying at least a portion of said cover member, said movement restraining member overlying said securable adjustment control when said movement restraining member is in said locking position;
• (b) a first mating locking surface defined by said movement restraining member;
• and
• (c) a lock comprising a movable locking member secured to one of said movement restraining member or said thermostat housing, said movable locking member being rotatable to engage a surface on the other of said movement restraining member or thermostat housing.
