Electric Analog Connections
Electronic controls are typically factory wired for single point power voltage supply with fan relay and 24VAC power
(from a step-down transformer) as part of the fan circuit or electric heater circuit.
1. The remote mounted thermostat is connected to the appropriate components located in the control box. See the
control wiring diagram affixed to the inside of cover.
2. When hot water reheat is used, the relay in the control box must be wired to the water valve actuator.
Electronic DDC Controls
(Factory-mounted, controls by others)
IMPORTANT All RS485 communication networks must be installed using twisted, shielded pair wiring. Each twisted
pair must be individually shielded. If using unshielded wiring, cables must be placed in solid metal conduit alone,
without DC switching or AC lines. Failure to use these types of connectors may result in various system
communication problems such as excessive network retries, noise susceptibility, and loss of communication.
If proper wiring is not used, the site may not meet FCC class A regulations for RFI emissions; thereby forcing the
installer or user to make the necessary wiring changes at a later date.
