A SEPARATE TH8110R1008 THERMOSTAT AND THM5421R1021 EIM ARE NEEDED FOR EACH WIRELESS ZONE. 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 TWO FEET APART.
THE TH8110R THERMOSTATS CAN BE COMPLETELY WIRELESS AND
POWERED BY FOUR AA ALKALINE BATTERIES, HOWEVER
IF THERE ARE
TWO WIRES AVAILABLE AT THE THERMOSTAT YOU CAN WIRE THOSE TO R AND C ON A TRANSFORMER OR ON THE R
AND C AT THE TOP OF THE EIM.
FOR WIRING OF THE VALVES, PUMPS, POWER, DOMESTIC HOT WATER
(IF USED), ETC. SEE THE OTHER DIAGRAMS IN THIS
FILE OR THE LITERATURE PACKED WITH THE PANEL.
