Before making any connections, identify the required connections to
and from the panel (see page 5 for adapter sizes). The supplied rubber
washers must be used.

then to the panel pipework.
Step 2 Connect MNPT adapter (not included) to copper pipe, or
tubing E.
Step 3 Screw supplied M×FNPT adapter C onto D using
appropriate thread sealant.
Step 4 Place included rubber washer B on flat surface of C, and
place against flanged edge of stainless steel pipe.
Step 5 Slide nut A over adapter C and finger tighten, then using
two 30mm wrenches tighten the nut - do not overtighten
the nut as this will damage the rubber washer.
Step 6 See page 14 for optional flow switch connection
instructions.

Aux(iliary) Contacts: The auxiliary contact set is dry, meaning no supply of power is present at the terminal. The
maximum allowable load is 10A. The auxiliary dry contact is for switching another device (ie. the heat source)
when there is a call for heat.
Flow Sw(itch) Contacts: The wiring harness of the optional Flow Switch for DHW Priority (FLWSWITCH) uses these
contacts (see page 14).

1. When the power cord 1and transformer 2are plugged in, the panel will be able to operate
properly.
2. The timer 3activates the primary pump for 15 minutes every 24 hours to ensure that potable
water in the piping is not stagnant.
3. When a thermostat calls for heat, its internal 24V contacts close, the relays close, and both pumps
4turn on.
4. When the requirements of the thermostat are met, the internal contacts of the thermostat open, the
auxiliary contacts open, and the pumps stop.

The HEP025RT features a timer which will activate the pump in order to circulate water within the
system for 15 minutes every 24 hours. This prevents stale water from accumulating in an open
system during periods of low heat demand (ie. summer).
It is recommended that any HEP025RT installed in an open system remain plugged in (with the
thermostat on low during summer periods) in order to allow the timer to activate this circulation.
If the HEP025RT is installed in a closed system it can be unplugged during these periods.
The timer is set at the manufacturing facility for this function, and should not be altered.
See insert for detailed Timer instructions.
