RH DIMENSIONS
RH
Recessed fan assisted heaters (ceiling or bulkhead)
Application
An RH heater is often used as an over door heater when there is insufficient space above the door to allow a conventional heater to be fitted or when a glass panel is positioned above the door making a conventional heater difficult to install and possibly unsightly. Equally they can be used as general space heaters in applications such as toilet blocks and lobbies.
Features common to all models
- Air inlet and outlet from the front panel - no requirement for air supply to the rear of the heater
- Simple fixing through the front face of the heater
- White (RAL 9016) aluminium egg-crate grille conceals the fixings
- Auto reset over temperature protection device
- Suitable for vertical or horizontal discharge
- 1m 3 core cable
RH-30 - Specific features
- Dimensioned for easy installation in a 600mm wide suspended ceiling grid
RH-60 - Specific features
- Built-in control contactor
- Convenient terminals to allow heater to be controlled by a conventional thermostat via the built-in contactor

RH-20 - Control options
- Wall mounted thermostat controlling an individual heater directly or a group of heaters via a suitably rated contector or relay. Ref. RST-IN
- Wall mounted (semi-recessed), 7 day programmable, electronic thermostat controlling an individual heater directly or a group of heaters via a suitably rated solid state relay or contactor. When using a contactor we recommend that a suitable snubber is installed in the control circuit. Ref. H16C
- Surface mounted remote controller providing 'on'/'off'/'High/'Low'/'fan only' settings. A 5 core cable will be required to connect the heater to the controller. Ref. CS-1
