CAUTION: The end of the cable, where the leads emerge from the sheath, is not water tight. To prevent seepage of water up the interior of the cable to the inside of the Waterpad, do not allow the end to be placed under water or in a wet location. The 6-foot cable allows sufficient length to pull the cable end to a compartment or room area where it can be connected to the 8-terminal block in a dry environment.

Power Management

Like the Smart Pad2 or 3, the Waterpad™ has the ability, via the STATUS terminal, to prevent unintended power turnoffs when power commands are sequenced with source commands.

•The Waterpad stops the first command in a sequence (the power command) when the STATUS terminal is high (+12V DC = ON).

•Conversely, when the system is OFF, the first command (power) will be sent since the STATUS terminal is low (0V).

•This assumes that +12V and 0V, representing a system ON and OFF condition, is applied to the STATUS terminal (see Fig. 5)

•See Fig. 3 for STATUS connections in a typical system.

NOTE: If power management is not used (i.e. 3-wire hookups), a short jumper must be connected between the STATUS and +12V terminals (see Fig. 5).

This powers the source button LEDs so they will come on with the selected bank. In this case, you must put the system power command under an ON/OFF button (not under the source buttons). Also, source commands must be placed twice under each source button in a 2-command sequence. The user will then need to make two initial button presses to start the system, one for ON and one to select the source.

Also, when programming the Waterpoad for control of the ZPR68, you will need to place the source select commands twice under each source button so that the sources can be selected after zone turn-on.

MOUNTING

The Waterpad is designed to mount into most standard 2-gang "J" boxes in basically the same way as other wall mounted decorator style components. The "J" boxes may be either of the new construction or retrofit varieties. Consider the following when planning the mounting of the Waterpad:

• The Waterpad requires considerable room in the J-box.
