ZONE THERMOSTAT CONTROL RELAYS — A unique feature of the Aquazone system control panel is the capability to add zone thermostat control relays. This feature is used when the Aquazone system control panel is utilized in a stand-alone type of installation. Either a set of 10 or 18 relays can be selected from the 50RLP model nomenclature in digit 9 to control either 10 or 18 zones, respectively. If selected in the model nomencla- ture, zone control relays are located on the right hand side of the system control panel. See Fig. 4. See Fig. 5A-5C for wiring.

CONTROL TRANSFORMERS — Control transformers are supplied with the Aquazone system control panel and are wired to the power switch and convenience outlet. The control transformers provide power to the nominal 24 VAC circuit in Aquazone system control panel. The contractor will supply the

primary power to the power switch and convenience outlet in the field. Transformers include a manual reset button for reset- ting the circuit breaker. Control transformers are located on the bottom half of the system control panel. Specifications for the control transformers are as follows:

Primary: 120/208/240 vac

Secondary: 24 vac

Frequency: 60 Hz

MOUNTING RAILS AND WIRING DUCT — All exposed panel wiring is low voltage. Line voltage wiring to the control transformers, control circuits for pumps, cooling tower fans, and boilers is factory-installed in conduit, using wiring duct, and on mounting rails.
