ENGO E7 Wireless Programmable Thermostat | E7-RFW | White

Description

The ENGO E7-RFW is a programmable wireless room thermostat kit in white, supplied as a E7-TXW thermostat and an E7-RX receiver that are factory-paired with unique communication codes and ready to commission. A large, easy-to-read display and simple 3-button control keep everyday use straightforward, the default day/night schedule gets a system running without any programming, and a full weekly schedule is available for more demanding users.

Communication runs on the 868 MHz band with an open-space range of approximately 100 m. The receiver's voltage-free NO/COM relay output (16(5) A) can switch a boiler's thermostat terminals, a circulation pump or a valve actuator, and the thermostat supports heating or cooling operation with TPI control (underfloor heating, radiators, electric heating) or hysteresis control. Backed by a 5-year manufacturer warranty from the date of installation.

Installation and safety

The receiver is powered from 230 V AC mains. Installation must be carried out by a qualified person with the appropriate electrical licence, in accordance with BS 7671 and the regulations in force. The receiver must not be installed where it is exposed to water or condensation, and the thermostat must not be used with a damaged housing or modified in any way.

Compatibility and on/off control

The receiver provides a voltage-free (potential-free) relay output for on/off control. When connecting to a boiler, use the boiler's own ON/OFF room thermostat contacts as described in the boiler instructions. Pump and valve actuator loads must stay within the 16(5) A rating of the receiver.

Temperature range note

The technical data lists a 5 - 35°C temperature range, while the installer parameters allow the minimum and maximum setpoint limits to be set anywhere between 5°C and 45°C (default maximum 35°C). Use the technical data range as the guaranteed operating range.

Also available in black

This listing is the white version. The same E7 kit is also available in black (E7-RFB) with identical functions and specification.

Key features

Factory-paired wireless link

Thermostat and receiver are factory-paired with unique communication codes, which prevents mutual interference. Communication uses the 868 MHz band, and the receiver automatically signals loss of contact with a flashing orange LED after 40 minutes without a signal.

Large display, 3-button control

A large, clear LCD shows room temperature, setpoint, clock, day, heating/cooling demand, receiver connection and battery status. Three buttons (-, OK, +) cover manual setting, schedule entry and installer settings.

Day/night and weekly scheduling

A default day/night schedule works out of the box. Switch to a weekly schedule with a separate programme for each day and a copy-to-next-day function, or keep one schedule for the whole week. A temporary override holds a new setpoint until the next schedule change.

Heating or cooling

Switch between heating and cooling modes with a button combination or in the installer settings. Animated heating and cooling icons show live demand on the display.

Choice of control algorithms

Select TPI for underfloor heating, TPI for radiators or TPI for electric heating, or hysteresis control with a range of selectable band settings. The offset adjustment of up to +/-3.5°C corrects the displayed temperature.

Locks, limits and flexible mounting

Key lock with optional PIN protection for installer settings, plus adjustable minimum and maximum setpoint limits. Mount on the wall with the included wall plate, or place it on the supplied stand as a stand-alone thermostat. Powered by 2 x AA alkaline batteries.

Frequently asked questions

Is the thermostat already paired with the receiver?

Yes. The kit is factory-paired with unique communication codes, so it is ready to use once installed. If you ever need to re-pair, power the receiver with both switches at ON and AUTO, flick the left switch to OFF and back to ON until the green LED flashes, then hold the - and + buttons on the thermostat for about 5 seconds until SY appears. Pairing can take up to 300 seconds.

What is the wireless range?

Approximately 100 m in open space. Thick walls, foil-backed plasterboard, metal cabinets and radio interference can reduce this. Test transmission before fixing the thermostat to the wall by raising and lowering the setpoint and watching the orange LED on the receiver.

Can I set a different schedule for each day?

Yes. By default one schedule applies to every day. Set installer parameter P12 to 1 for a separate schedule per day, then use the copy function to repeat a day. When using per-day programmes, all days of the week must be programmed.

Can it be used for cooling as well as heating?

Yes. Hold the - button and OK button together for 3 seconds to switch between heating and cooling, or use installer parameter P01. The display icon changes to show the active mode.

What happens if the batteries go flat or the signal is lost?

The thermostat shows a battery indicator. If the receiver has not heard from the thermostat for 40 minutes, its orange LED flashes to show the connection has been lost, for example through poor range or depleted batteries.

Can I lock the buttons?

Yes. Hold OK and + for 3 seconds to lock or unlock the keys. You can also enable a PIN code for installer settings (P09) and require it to unlock the keys (P11).
