Important Notes

It is extremely important to use good quality batteries in the eTRV and eTRV-HW to ensure
correct operation of the product. EPH recommend using Li-FeS (Lithium Iron) batteries. If poor
2
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 noti cation will appear on the eTRV, eTRV-HW and on the EMBER app. The batteries should be
changed immediately. Normally the eTRV will stop operating soon after this noti cation. When the
eTRV / eTRV-HW 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.
Li-FeS (Lithium Iron) batteries are available from www.ephcontrols.com

The eTRV and eTRV-HW detect temperature and communicate on cycles every 4 minutes to
conserve battery power. When buttons are pressed on the eTRV and eTRV-HW it will save these
changes but may not communicate immediately to the RF16. It will communicate these changes on
the next communication cycle.
The eTRV is designed for use with EPH TRV Valve bodies.
