Diagram 1 INSTALLATION AT OR NEAR THE HOT
WATER SOURCE: TempControl must be positioned
below the hot water tank or heater, well below the high
temperature water line. This procedure creates a heat
trap and protects against hot water migrating through
the controller.

Diagram 2 INSTALLATION WITH RECIRCULATING
TEMPERED WATER AT HOT WATER SOURCE: Temp-
Control must have the return line connected exactly as
shown. This procedure allows the controller to maintain
the set temperature during periods of no draw by (a)
allowing the major volume of return water to supply the
cold inlet of the TempControl and (b) the minor volume
of return water to be reheated and supply the hot inlet
of the TempControl. When there is no water draw on the
plumbing system, no water can be added to the system;
therefore, the "cold" and "hot" supplies to the Temp-
Control must come from within the system as described
below using the ball valve for fine tuning the operation
as outlined in (a) and (b).
