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. [. . . ] · 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. Check the boiler supply is on and check that the green LED on the receiver box is off. 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. The boiler will go off (green LED OFF on receiver box) after a few seconds and the symbol disappears. 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. These are all listed in section 4. 5 Installer Parameters Table.

[. . . ] If the red LED still flashes push the button again until binding is successful. Now go to Section 2) Installing the CM900 Wireless System to setup the system. 5. 2 Multi-Zone System Multiple room thermostats and receiver box sets can also be used to control multi-zone systems and the CM927/921 room thermostat is compatible with a variety of other Honeywell products including HR80 radiator controllers and HCE80 underfloor heating controllers. If you intend to use it in this way additional installation and user instructions can be obtain by contacting the address at the end of this guide. NOTE: Some of the labels supplied with the pack are for use in multizone applications.
