The control buttons perform the following basic functions:
Decrease / Increase value: by default this adjusts the set temperature. When the set temperature is adjusted
above the measured room temperature, the heater active symbol is shown and any paired heaters are
switched on.
Mode: cycle through operating modes Boost, Manual, Setback and Program (see sections 6-9).
By default Setback mode is disabled (see section 8).
Fan: cycle through fan speed settings (for fan heaters only). No fan symbol shown means low speed, one fan
symbol is medium speed, two fan symbols is high speed.
Pressing fan when heating is inactive will activate fan only mode (for compatible fan heaters).
In fan only mode, FAN is shown on the display. Exit fan only mode by cycling through the fan speed
settings until FAN is not shown.
Programme: used for advancing programme, setting the time and accessing programming menu.
Important display icons:
Heat icon: this is displayed when the heating is active. RX heaters will operate at reduced heat output when
close to the set temperature, and half the icon is shown:
Lock symbol: this is displayed when the CRXSL controls are locked. Hold and
together for 5 seconds to
unlock or lock the controls.
ALARM!
Flashes to indicate an error in the programme setup, e.g. the time for programme 2 is set earlier than the
time for programme 1.
2. Getting to know your CRXSL wireless controller
The CRXSL Wireless Controller can control any ‘RX’ or ‘SL’ heater, including multiple products at the same time.
The CRXSL must be paired to each heater, otherwise the heaters will not work
(see section 3).
For options for powering the CRXSL see section 18.
