Li-FeS2 (Lithium Iron) batteries available from www.ephcontrols.com EPH Controls Ltd. 5 Important Notes It is extremely important to use good quality batteries in the eTRV to ensure correct operation of the product. EPH recommend using Li-FeS2 (Lithium Iron) batteries. If poor quality batteries are used, they may cause the product to stop communicating wirelessly, fail to communicate information correctly and stop opening or closing. Low power or discount store battery brands should not be used. When the battery is low a battery low notification will appear on the eTRV, it will also display on the EMBER app. The batteries should be changed immediately. Normally the eTRV will stop operating soon after this notification. When the eTRV shows a fault E4 the motor is not operating correctly, this is normally due to a battery issue possibly one or both of the batteries are not providing adequate power. The eTRV detects temperature and communicates on cycles every 4 minutes to conserve battery power. When buttons are pressed on the eTRV it will save these changes but may not communicate immediately to the RF16 controller. It will communicate these changes on the next communication cycle. The eTRV is designed for use with EPH TRV Valve bodies. 6 eTRV How your eTRV works The eTRV is designed to control and operate a radiator valve wirelessly. When the eTRV is calling for heat, it will communicate wirelessly to the RF16 controller which will activate your heating system to heat the radiator. When the eTRV reaches its defined setpoint temperature it will close the radiator valve and stop calling for heat. The temperature setpoint is defined by the program settings on your RF16 controller, via the EMBER app or by using the and buttons on the eTRV. If the room temperature is lower than the target temperature then the eTRV will open the radiator valve and request the heating system to activate, if the room temperature is higher than the set temperature it will close the radiator valve and signal the system to stop calling for heat. When calling for heat your eTRV will show a flame symbol on the screen. This will disappear when the temperature setpoint has been achieved. When the eTRV is in MANUAL or AUTO, the screen will display the current room temperature. When the eTRV is in the OFF mode the screen will display the word `OFF'. EPH Controls Ltd. 7 Mounting & Installation Caution! Ensure the eTRV is positioned in an area that has good air flow so it can detect temperature effectively. Ensure the eTRV is out of direct sunlight. If the eTRV or RF16 are used in a way not specified by the manufacturer, its safety may be impaired. Prior to setting the eTRV, it is necessary to complete all required settings described in the mounting & installation section. Ensure the valve body is free of dust and debris. Ensure the valve body is dry and not leaking. 1 2 3 8 4 Vertical Position Horizontal Position IN OUT (flow) (return) IN OUT (flow) (return) eTRV 1) Press and hold the release mechanism on the side of the eTRV, while holding pull the cover up and it will slide off the eTRV. 2) Insert the 2 x AA batteries and replace the cover. Pair the eTRV to the RF16. (see page 18) - Mark the eTRV zone by using the stickers provided. - Note the room name on the 16 zone list provided, this will help the user of the system identify the zones if it's needed in future. 3) The eTRV can be mounted to a radiator valve with a M30 x 1.5mm thread. Rotate the ring at the base of the eTRV so it threads onto the radiator valve until it's tight. It will automatically adapt its stroke to that of the valve. It's recommended that the eTRV is opened to make it easier to mount, this is done by calling for heat on the RF16 or eTRV and it will retract the spindle. 4) Position the eTRV on the radiator valve so the screen is orientated correctly. Note: The eTRV is designed for use with EPH TRV Valve bodies.
