⚡ At a Glance
- • Temperature Control: Dual diaphragm sensing element ensures close temperature regulation within the 10 to 30°C set point range
- • Best for: Installers and homeowners replacing older thermostats who need simple, reliable on/off control
- • Not ideal for: Systems requiring programmable schedules or integrated smart-home connectivity
Mechanical on/off control supports gas boilers, circulation pumps, relays and zone valves. Designed for wall or conduit box mounting with easy-to-wire terminals and a heat anticipator for close control.
Precise temperature regulation, thanks to the dual diaphragm sensing element
Dual diaphragm sensing uses two linked diaphragms to detect small temperature changes and commands switching quickly. The sensing arrangement reduces overshoot by reacting to rising or falling ambient temperature.
Consistent room temperatures reduce noticeable swings and short cycling, improving comfort. Close control suits systems with higher heating ramp rates.
Reliable on/off switching, with change-over contact and heat anticipator
Change-over contact switching handles cooling loads as well as heating, allowing simple switching between modes. The heat anticipator tempers the control action on fast-ramping heating systems to avoid overshoot.
Suitable for boilers, pumps, relays and zone valves that need robust mechanical switching. Expect steadier temperatures where rapid heat gains would otherwise cause overshoot.
Quick, secure installation, with wall or conduit box mounting and built-in conductor clamps
Mounts directly to a wall or standard conduit box, and terminals include conductor clamps that retain wiring securely during connection. Mounting screws are provided to simplify replacement.
Straightforward swap-in for older thermostats shortens installation time and reduces risk of loose connections. Both DIYers and professional installers benefit from the practical wiring design.
