CONSORT CRXSL-05 Single Zone Wireless Controller User Guide

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.

Getting to know your CRXSL wireless controller

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.

Pairing CRXSL with heaters

This must be done, otherwise the heaters will not work.

Power up the CRXSL (see section ‘Power options’ for details).
There are 2 different sequences used for pairing. The sequence used will depend on the heater.
To find out which sequence to use, check the heater rating label and identify the model number.

If the heater is ‘RX’ and the last two digits are lower than 10 use sequence 1.
If the heater is ‘RX’ and the last two digits are 10 or higher use sequence 2.
If the heater is ‘SL’ use sequence 2.

If the rating label is not visible, follow the steps below:
Ensure the heater is switched OFF.
Switch the heater ON and observe the LED status light.
If the LED flashes red then goes green use sequence 1.
If the LED is solid green use sequence 2.

Setting 14 should be changed to 1 to enable.

MRX1 Multizone controller

The CRXSL controller is compatible with the MRX1 Multizone controller. Please refer to the instructions of the MRX1 when connecting the CRXSL controller to the MRX1.

Choosing a position in a room

The CRXSL should be fixed to the wall or used with the table top stand. Avoid areas with draught or direct sun. Do not position CRXSL above or close to the heaters or other heat sources. Damp areas or areas where CRXSL can be mechanically damaged should also be avoided.

Power options

Please note that the controller screen will take up to one minute to display after powering up for the FIRST time.

The CRXSL controller can be powered either by a 5V power adapter with a micro USB connector, supplied power adapter via USB port or 4 AAA batteries. There are 2 available USB ports for power. One port is located on the bottom and one at the back of the controller.

The display will show the battery status only when the CRXSL is powered by batteries alone.

Batteries

Remove the CRXSL’s battery cover and insert 4 new high quality alkaline AAA batteries.

Warning: Consort is not responsible for damage due to corrosion. Battery leakage will cause permanent damage.

To help avoid battery leak:

Replace the batteries annually, even if there is not a low battery warning. Remove failing or flat batteries immediately.

Always fit new high quality alkaline batteries from the same pack. Never mix new and old batteries, or batteries of different brands or types.
Never attempt to revive alkaline batteries by heating, crushing or recharging.

Note: The clock has to be set after replacing the batteries, or if the USB power cable has been disconnected from the CRXSL or power to the power adapter switched off. This does not apply if it is being used with the MRX1 Multizone controller. If the CRXSL is powered by the power adapter, 2 AAA batteries can be used to supply power in the event of a power cut in order to keep the clock running. The batteries should be replaced annually.

Power adapter for fixed installation

The CRXSL controller is supplied with a power adapter that will fit a 35mm or a 25mm metal or dry lining back box. The power adapter should only be connected to a wiring protected by a 6A fuse or 6A circuit breaker. Connect line and neutral conductors to the terminal block. Please note that the adaptor supplied with the controller must be installed exactly as the figures show, otherwise the USB connector will not fit correctly. The centre of the back box must be kept clear to allow room for the USB connector.

When fitting the wall bracket, ensure that the adaptor is installed properly and feed the cable through the centre of the bracket. Screw the bracket to a back box taking care not to damage the power adaptor or leads with long screws. Connect the USB cable into the power port at back of the controller as shown on the photo. Check that the CRXSL is working. Attach top of the CRXSL to the wall bracket and slowly tilt it to place observing that the USB connector is moving in to the opening freely. Once the controller is in place secure the two screws on the bottom of the controller.

When the unit is powered by the power adapter, the temperature reading should be calibrated 1.5°C / 3°F lower.

To do this a setting in the setup menu needs to be changed (see section 21).

Setting 01 should be changed to –1.5°C.

Open Window Detection

To ensure you don’t waste energy on heating the outside world, the heater is equipped with an optional open / closed window detection. The heater recognises sudden drops in temperature when a window or a door is opened and turns the heating off to save energy. When the window is closed, the heater will automatically detect a temperature rise, and switch itself back on. Once enabled in the setup menu, the open window detection is fully automatic and does not require any human intervention to be activated.

Setting-up Open Window Detection

The system has been factory set to default time and temperature values. When the heating is on, open window detection sensor will automatically switch the heater off when it detects a fall in temperature of 2°C in less than 10 minutes. If a temperature rise of 2°C in less than 30 seconds is detected, the heater will switch itself back on. These values can be adjusted in the setup menu, detailed in section 23.
Settings 07-11 control open window detection.

Manual Control Mode (Selected heaters only)

The CRXSL can also operate in Manual Control Mode.

In this mode, heat and fan settings can be manually set, and the room temperature is not used to switch the heaters.

The fan speed F0, F1, F2 or F3 is displayed on the left side of the display. Press to cycle through the fan settings.

The heat setting H0, H1, H2 or H3 is displayed on the right side of the display. Press or to adjust the heat setting

In Manual Control Mode, many of the functions of the CRXSL are very similar to automatic mode, except that the fan and heat settings are adjusted instead of the set temperature:

Boost mode can be used to temporarily override the heat and fan settings.
Programmes can be set up with up with the same flexibility as in automatic mode.

Manual mode can be used to run the heaters continuously in one heat and fan setting.

Manual Control Mode is accessed by changing a setting in the setup menu (see section 23).
Setting 06 should be changed to 2.

Simplified Automatic Mode

As shown on the setup menu in the previous section, the CRXSL has two different automatic modes. These are simplified automatic mode and automatic mode.

In automatic mode, all information can be seen at all times. This information includes the room temperature, target temperature, the time, day, operating mode etc.

Having all this information available is useful, however it can be overwhelming. This is what simplified mode is for. In simplified mode, the CRXSL will only display information essential to the usage of the controller.

By default, the CRXSL will be in simplified automatic mode.
