Caution Improper installation and operation of this control could result in damage to the equipment and possibly even personal injury.
If the control is to be mounted on an electrical box, the wiring can be roughed-in at the electrical box prior to installation of the control see Brochure D Standard 18 AWG solid wire is recommended for all low voltage wiring to this control. The sensor should be placed approximately 3 feet 1m from the edge of the slab.
It is your responsibility to ensure that this control is safely installed according to all applicable codes and standards. Do not connect the wires to the terminals yet.
Testing and connecting the wiring Caution These tests are to be performed using standard testing practices and procedures and should only be carried out by properly trained and experienced persons.
Turn on the 24 V ac power supply and, using a voltmeter, you should measure between 20 and 28 volts between the power and common terminals. Test the sensors according to the instructions printed in the enclosed Data Brochure D Step Three Rough-in wiring All electrical wiring terminates in the two wiring chambers at the bottom front of the control.
A Class 2 transformer must be used. Step One Getting ready Check the contents of this package. A good quality electrical test meter, capable of reading from at least 0 — Volts, and at least 0 — 2, Ohms, is essential to properly test this control.
Do not connect either of the transformer secondary wires to ground. This electronic control is not intended for use as a primary limit control. At no time should voltages in excess of 28 V be measured at any of the wires connected to the control. Run the wiring back to the control but do not connect the wires to the terminals yet.
