improve the of use this product includes an extra large display with backlighting and LoT Technology assist customers during daily use CM927 921 room thermostat communicates the BDR91 Relay Box on an 868MHz Radio RF band to control a single heating component such as a boiler pump or valve Neither product will communicate with RF products that use different frequencies or protocols The RF link between the individual room CM927 921 and Relay Box BDR91 system packs provided by Honeywell is pre at the factory and therefore SHOULD installed at the same site This makes the process fast and easy but if products individual system packs are separated or with other pre configured system packs installations please refer to section 5.1 Rebinding Procedure to bind the desired together and allow

installation The of the RF components as well as the building structure may influence performance of the RF To assure system reliability please review and apply the information given below a typical residential building the two products should communicate reliably within a 30m range It important to take into consideration that walls and ceilings will reduce the RF signal The strength of RF signal reaching the Relay Box depends on the number of walls and ceilings separating it from the thermostat as well as the building construction the diagram below illustrates an example of typical strength reduction Walls and ceilings reinforced with steel or plasterboard walls lined with metal foil the RF signal significantly more a position is selected for the room thermostat this can be checked using the RF Communication Test as described in section 2.2.3 Locating the Room Thermostat If the position is unsuitable the Relay will not respond and an alternative position must be selected Signal
