A SEPARATE THX9421R5021 THERMOSTAT AND THM5421R1021 EIM ARE NEEDED. THE THERMOSTAT AND EIM ARE SOLD
TOGETHER IN THE YTHX9421R5085 KIT.
THE EIMS GET MOUNTED ON A WALL IN THE UTILITY ROOM WITH THE HYDRONIC PANEL. TO ENSURE WIRELESS
COMMUNICATING RELIABILITY, WE RECOMMEND THE EIMS BE SPACED AT LEAST 2 FEET APART.
THE EIM WIRING IS THE SAME FOR ALL THE HPZ AND HSR HYDRONIC PANELS. FOR WIRING OF THE VALVES, PUMPS, POWER,
ETC. SEE THE OTHER DIAGRAMS IN THIS FILE OR THE LITERATURE PACKED WITH THE PANEL.
