To further improve the ease of use, this product includes an extra large LCD display with backlighting and LoT Technology to assist customers during daily use. The CM927/921 room thermostat communicates with the HC60NG receiver box on an 868MHz Radio Frequency (RF) band to control a single heating system component such as a boiler, pump or zone valve. Neither product will communicate with other RF products that use different frequencies or communication protocols. Note: The RF link between the individual room thermostat (CM927/921) and receiver box (HC60NG) in system packs provided by Honeywell Home is pre-configured at the factory and therefore SHOULD be installed at the same site. This makes the installation process fast and easy, but if products from individual system packs are separated, or mixed with other preconfigured system packs during installations please refer to section 5.1 Binding / Rebinding Procedure to bind the desired units together and allow them to communicate with each other.

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

NOTE: If the green LED is not switched at specified intervals, the red LED is flashing or if you are installing a replacement receiver box or room thermostat, follow the procedures described in section 5.1 Binding / Rebinding Procedure. 4 CM900 Wireless - Programmable Room Thermostat 2.2.3 Locating the Room Thermostat While still in the Test Mode, as described in section 2.2.2, the room thermostat should be located taking the following into consideration and reviewing the illustrations below: 1. Find a suitable location where the signal transmission is reliable. Reliable transmission is indicated when the receiver box is flashing the green LED every 6 seconds. NOTE: The receiver box relay will be off. 2. Install the room thermostat EITHER on the wall using the wall bracket OR attach the optional table stand as shown in below. 3. Exit the Test Mode by moving the setting slider to the required operating mode (AuTO or OFF). Wall bracket Table stand · The room thermostat should be installed in an open space for best performance as it is a radio frequency device. · Leave at least 30cm distance from any metal objects including wall boxes and at least 1 metre from any other electrical equipment eg. radio, TV, PC etc. · Do not mount onto metal wall boxes. · It is recommended that the receiver box is fully installed. 2.3 System Check Now a simple test can be completed to check the full system has been installed correctly: 1. Set the slider switch to the OFF mode. 2. Check the boiler supply is on and check that the green LED on the receiver box is off. 3. Set the slider switch to the MAN mode. 4. Adjust the setpoint up to the maximum (35°C) by pressing the button. The boiler should come on (green LED ON on receiver box) after a few seconds and the symbol appears on the room thermostat LCD display. 5. Set the slider switch to the OFF mode. The boiler will go off (green LED OFF on receiver box) after a few seconds and the symbol disappears. 6. Check the system operation by moving the slider between MAN and OFF modes several times, bearing in mind the switching delay referred to above. Now, you should have completed the installation successfully - to begin operating at the default factory settings move the slider to the AuTO mode or select PROG to modify the built-in heating program accordingly. Installation Guide 3) Basic Operation of the System 3.1 Automatic Operation The receiver box receives the heat demand (0100%) signal from the room thermostat. The room thermostat will display the symbol on the LCD display whenever more heat is required. Depending on the demand the receiver box will switch the heating device on to match the current requirements of the system. The green LED indicates the status of the relay output: · Green LED on = relay on · Green LED off = relay off HC60NG Receiver Box Push button and relay status LED's 3.2 Temporary Manual Override Pressing the receiver box button will override the current relay position. As soon as the next signal is received from the room thermostat the receiver box will return back to automatic operation as the automatic control has higher priority than manual operation. 3.3 Communications Loss If the RF communication is lost for a period of 1 hour the red LED will illuminate to indicate that no RF messages have been received during the last hour. The receiver box will also enter the failsafe mode as selected in Installer Mode (see section 4.2 HC60 Receiver Box Fail-Safe Mode Setup). To allow manual control of the receiver box output manual override is available in fail-safe mode. When RF communication is restored the receiver box will automatically return to normal operation. You can now use the USER GUIDE supplied with the room thermostat to demonstrate how it works to the home owner. 4) Installer Mode Installer Mode is used to alter the system settings for specific applications, to use the special features of the room thermostat in a different way or to alter the factory preset parameters. Parameters are divided into two groups: - Category 1 parameters Room Thermostat Setup - Category 2 parameters System Setup.
