HWE-SS Plumbing and Wiring Diagrams

Mechanical

Electrical

NOTES:

•   The HWE-SS does not source any output power 

to any of its relays. A power source must supply 

pumps with power and the control can break the 

hot leg.

•   Heat-Timer recommends using a separate power 

source to the control from any pumps, boilers, 

heavy electric equipment.

•   When wiring a sensor to the HWE-SS, connect the 

Shield to the COM terminal on the HWE-SS end.  

DO NOT connect the Shield at the sensor end.

•   Heat-Timer is aware that each installation is 

unique. Thus, any wiring or piping diagrams in 

this document are to represent control opera-

tion concept only.
