Radio Signal and Location

Consideration for the location of your Smart Sensor and Receiver is crucial for optimal radio signal performance. The signal travels in a straight line and degrades with distance and obstructions.

If WiFi signal strength is poor at the Receiver location, consider upgrading your WiFi network. Visit www.inspirehomeautomation.co.uk/wifi for assistance.

The Smart Sensor communicates with the Receiver via low-power radio (RF). The system should generally work through up to two single-skin brick or stud walls. For extended range, consider an Ignite Signal Booster: www.inspirehomeautomation.co.uk/signal_booster.

Diagram Description (Fig 1): Illustrates three sensor locations (A, B, C) and signal paths. Location A, passing through two external walls, is poor (❌). Location B, through a solid wall, is very poor or non-existent (❌). Location C, through one internal wall, provides a significantly better signal (✔️).

Smart Sensor Placement

Diagram Description (Fig 2): The Smart Sensor should ideally be mounted on an internal wall at a height of 1.5m in a high-traffic area. Avoid placement near draughts (front door, windows), heat sources, or direct sunlight.

The Smart Sensor must not be installed in high humidity areas (e.g., bathrooms, shower rooms) as steam can cause erratic readings, condensation, irreparable damage, and battery corrosion/short circuits.

System Requirements

Rooms with Smart Sensors must have a working radiator with the Thermostatic Radiator Valve (TRV) removed, if present. TRVs can typically be removed by turning them to maximum, pushing down, and undoing the metal collar.

Diagram Description (Fig 4): Recommends placing the Receiver at least 1 metre away from metal objects like boilers or hot water cylinders. Do not install underneath the boiler to prevent water damage.

The Receiver must also not be installed in high humidity areas for the same reasons as the Smart Sensor.

Installation

Before commencing work, isolate the existing power supply.

To access the internal components of the Receiver, undo the two screws on the front cover and lift it off.

The unit is designed for fixed wiring. For surface mount cable, break out the tab underneath the unit and secure the cable(s) with the provided clamp. Surface mount cable should be clipped to the wall or run in suitable trunking. Use 1mm² cable and ensure no bare copper is visible outside the connector block. All wiring must comply with current IEEE wiring regulations.

The Ignite Receiver is a Class 2 device and does not require an earth connection. Existing earth leads may need to be joined using a terminal strip for continuity. Ensure the circuit is protected by a 3 amp fuse.

Installation - 2ch Series: Combi Boiler Without Room Thermostat or Timer

(Boiler switches on when hot tap is opened, no hot water cylinder)

Install the Ignite Receiver as per "Installation - Receiver" on page 13. If internal timers are present, they should ideally be disconnected. Consult your boiler manual for wiring external controls. Typically, a wire link on the boiler terminal block needs to be removed, and then two terminals are wired to terminals 3 & 4 on the Inspire Terminal board (as shown in Fig 5).

Connect the Receiver's Live (L) and Neutral (N) to the same fused spur as the boiler.

Diagram Description (Fig 5): Illustrates wiring connections for a 2ch series combi boiler without thermostat/timer, showing the Receiver's terminals and connections to the boiler.

Combi Boiler Wiring Methods

Most combi boilers can use a 4-wire installation. For 3-wire installations, refer to Fig 6, ensuring any boiler link wire is removed and a link wire is added between Receiver terminals 4 & 5.

After wiring, replace the front cover, secure with two screws (DO NOT OVERTIGHTEN), and restore power.

Diagram Description (Fig 6): Illustrates wiring connections for a 2ch series combi boiler with an existing room thermostat.

Combi Boiler With Existing Room Thermostat

• Wired Thermostat: Remove existing thermostat wiring from the boiler. Follow steps for "Combi Boiler without Room Thermostat or Timer" on page 7.
• Wireless Thermostat with built-in receiver (e.g., Drayton LP10RF): This unit must be removed from the boiler. Follow steps for "Combi Boiler without Room Thermostat or Timer" on page 7.
• Wireless Thermostat with external receiver: Note existing wiring locations at the old receiver, then remove it. Install the Ignite Receiver as described on page 13. Connect previously identified wires to the appropriate terminals. For 4 wires, see Fig 5. For 3 wires, see Fig 6, adding the link wire between terminals 4 & 5.

After wiring, replace the front cover, secure with two screws (DO NOT OVERTIGHTEN), and restore power.

System Boiler with Existing Controls

**Before commencing, take clear photos of the existing programmer wiring.**

S Plan: Typically 4 wires (Live, Neutral, CH ON, HW ON) to the programmer, usually near the hot water cylinder with 2 x 2-port zone valves.

Y Plan: Typically 5 wires (Live, Neutral, CH ON, HW ON, HW OFF) to the programmer, usually near the hot water cylinder with 1 x 3-port zone valve.

Existing programmers usually have 6 or 8 terminals (plus an earth terminal). Refer to the programmer's wiring schematic (Fig 7). Identify and label each wire according to its function (Live, Neutral, CH ON/OFF, HW ON/OFF). If the programmer has 8 terminals with 'C', 'Com', or 'Common' linked to Live, ignore these links. If using NO/NC notation, NO = ON, NC = OFF.

Diagram Description (Fig 7): Shows example wiring for a system boiler with existing programmer controls, illustrating terminal connections.

Once wires are identified, remove old wiring and install the Ignite Receiver as per page 13. Connect identified wires to the appropriate terminals (see Fig 8). For example, a black wire in terminal 4 of the old programmer ("CH ON") connects to terminal 3 ("CH ON") on the Ignite Receiver.

Add a link wire between Receiver terminals 4 & 5.

After wiring, replace the front cover, secure with two screws (DO NOT OVERTIGHTEN), and restore power.

Diagram Description (Fig 8): Illustrates wiring connections for a system boiler, mapping old programmer terminals to Ignite Receiver terminals.

Important: If a wired Room Thermostat is present, its wiring must be removed at the wiring centre, and the thermostat terminals (Live and Switched Live/Call) should be linked.

System/Combi Boiler with Existing Controls (4-Zone)

**Before commencing, take clear photos of the existing programmer wiring.**

A multi-zone setup is often wired as "S Plan Plus" (one 2-port zone valve per zone). This typically involves 2 power wires and one additional wire per zone (e.g., Live, Neutral, CH1, CH2, CH3, HW).

Existing programmers usually have 6 or 8 terminals (plus an earth terminal). Refer to the programmer's wiring schematic (Fig 9). Identify and label wires by function (Live, Neutral, CH1, CH2, HW, etc.). For 8-terminal programmers with 'C', 'Com', or 'Common' linked to Live, ignore those links.

Diagram Description (Fig 9): Shows example wiring for a system/combi boiler with existing programmer controls for multi-zone setups.

Once wires are identified, remove old wiring and install the Ignite Receiver as per page 13. Connect identified wires to the appropriate terminals (see Fig 10). For example, a yellow wire in terminal 1 of the old programmer ("CH1 ON") connects to terminal 1 ("CH1") on the Ignite Receiver.

Note: The "HW indicator LED" corresponds to Zone 4. It is recommended to wire the Hot Water Zone to terminal "CH4/HW". For a 3-zone timer with zones 1 & 2 as heating and zone 3 as hot water, connect zones 1 & 2 to CH1 and CH2, and zone 3 to CH4/HW. CH3 would not be used in this scenario.

After wiring, replace the front cover, secure with two screws (DO NOT OVERTIGHTEN), and restore power.

Diagram Description (Fig 10): Illustrates wiring connections for a system/combi boiler, mapping old programmer terminals to Ignite Receiver terminals for 4-zone setups.

Important: If a wired Room Thermostat(s) is present, its wiring must be removed at the wiring centre, and the thermostat terminals (Live and Switched Live/Call) should be linked.

New Heating System Without Existing Controls

For new heating systems without existing controls, it is recommended to wire as an "S or Y Plan" (2ch series) or "S Plan Plus" (4ch series). For more information, visit www.inspirehomeautomation.co.uk/newboiler.
