Installation

The MIHO069-W Requires direct connection of the Receiver to the boiler for it to function. The Thermostat can be powered either by battery, or USB supplied power.

Receiver Connection

Turn Off and isolate the power to the combi-boiler, central heating supply or electric heater.
Remove the existing thermostat, if fitted
Position the backplate on the wall, fixing in place using scrws provided.
Terminate the cables to the Receiver as shown in the wiring diagram.
Connect the Live Neutral and Earth from the boiler (or existing thermostat supply) to the Live Neutral and Earth on the left side of the backplate.
Connect the Live and Switched Live for your Room Thermostat connections to the Central Heating (CH) Normally Open (NO) and COM terminals on the connection box. If the cable is rigid, you should be able to insert them directly (Alternatively, use the Normally Closed (NC) terminal if it is required for your specific boiler).
Connect the Live and Switched Live for your Hot Water connections to the Hot Water (HW) Normally Open (NO) and COM terminals on the connection box. If the cable is rigid, you should be able to insert them directly (Alternatively, use the Normally Closed (NC) terminal if it is required for your specific boiler).

N.B. Each manufacturer uses different connections on their boilers for the room thermostat and if you are unsure of the connections to your boiler, you should seek assistance from a qualified boiler installer.
