INSTALLING THE ON COMMAND STARTER BUTTON
The manual starter button is a unique feature to the On Command. The “on-command”
start to the circulating pump maximizes energy savings and controls operation only when
there is a request for hot water as compared to automatic timer controlled systems.
1. Drill a
5
⁄
8
" hole into the desired location, typically the side or
front of a vanity cabinet.
2. Insert the gray wire from the controller through the back side of
the hole and connect it to the starter button.
3. Firmly insert the button into the drilled hole.
Note: To operate the On Command from other locations
throughout the house, additional starters can be installed and
spliced into the gray wire provided. Or for wireless remote
operation, the Taco #554-1 transmitter/receiver kit can be eas-
ily installed. See “WIRELESS REMOTE KIT OPTION” below for
instructions.
4. If wireless remote kit is not installed, use electrical tape or wire nuts to isolate the
three leads (black, white and green) on the black wire.
COMPLETING YOUR INSTALLATION
1. Turn on the water supply at the main. Check the system carefully for possible leaks.
If leaks occur, check all compression and threaded connections and tighten firmly.
Open hot and cold fixtures for one to two minutes to flush system completely.
2. Plug in the On Command to the 110V electrical outlet. The pump will start automatical-
ly the first time only and run for a short time until a rise in temperature is detected by
the thermal sensor. Pump will automatically shut off.
Note: When the On Command
is operating a green LED located on the pump motor housing will illuminate.
The Green LED will only be “on” when the pump is activated and circulating
water.
3. To test manual starter button, wait for hot water temperature to cool below 100°F
(approximately 20-30 minutes). Press starter button to operate the pump. The On
Command should run for a short time and shut off automatically as in step 2 above.
4. Check hot water at the fixture for desired temperature. If hot water temperature is
not satisfactory, refer to Trouble Shooting checklist section.
WIRELESS REMOTE KIT OPTION – MODEL #554-1
Wiring the Receiver:
The optional remote receiver kit is the white rectangular box with
the three protruding wires (black, white and green). Batteries are
not required. Wire the receiver directly to the corresponding wires
on the controller by twisting each same colored wire together with
gray wirenuts provided. Receiver should be mounted toward front
of cabinet. (Range of transmitter is about 70'.) If transmitter will
activate pump from short distance, but not from further away,
receiver may need to be relocated for better reception. Strapping
receiver to front of drain trap facing outward will optimize reception.
Installing Batteries to the Transmitter:
Open transmitter by inserting a small flathead screwdriver into slot to release catch.
Load battery with negative side of battery toward spring. Carefully replace cover.
Numbered jumper pins are inside the transmitter and receiver. The signal frequency can
be changed by removing the same numbered pins from both the receiver and transmit-
ter. This should only be necessary when two On Command pumps are in the same
home or neighboring homes.
For Additional Wireless Transmitter Buttons use Model #554-2.
