Stops unauthorised adjustments – thanks to key lock with inner shelf
A keyed lock secures the casing while an internal shelf blocks direct access to buttons and dials, preventing tampering. The lock uses a conventional key mechanism for controlled access.
Prevents accidental or deliberate changes to temperature settings, keeping heating schedules stable in shared or public areas. Suitable where consistent thermostat programming matters.
Flexible installation – with horizontal or vertical mounting options
Mounting brackets accept both orientations and use standard fixings to attach to the wall. The internal cavity accommodates thermostats up to 8.25in x 5.75in x 2.75in.
Adapts to different wall and panel layouts, making it straightforward to install in halls, utility rooms or offices. Reduces the need for custom fittings.
Durable visibility – with chemical and UV-resistant clear plastic
The clear plastic casing is formulated to resist chemical exposure and UV light that typically cause yellowing and loss of transparency. Transparency remains good for visual checks of displays without unlocking.
Maintains a neat, professional appearance while allowing quick visual monitoring of thermostat settings. Suitable for locations where appearance and readability matter.
