ViewStat Installation and Wiring

This section covers the installation, wiring and checkout of a ViewStat Communicating Thermostat System.

1.120 volts may cause serious injury from electrical shock. Disconnect electrical power to the HVAC system before starting installation. This system is a low-voltage system.

2.Improper installation may cause serious injury from electrical shock. This system must be installed by a qualified contractor in accordance with NEC Standards and applicable local and state codes.

Disconnecting Power to All HVAC Equipment

Since the ViewStats are wired directly to the HVAC equipment, the power must be shut off at the equipment. This can generally be accomplished by turning off the disconnect switch located near the equipment. If an obvious disconnect switch is unavailable, you will need to remove the circuit breaker or shut down the fuse serving the equipment.

Failure to disconnect power could result in damage to the HVAC equipment or thermostats. Leave power disconnected until all other electrical connections have been made and checked for accuracy.

Selecting the Thermostat Location

Determine if the thermostat will be operating alone, or with remote temperature sensors. If the unit is stand- alone there are certain measures that must be taken to ensure accurate temperature control.

Stand-alone thermostat mounting criteria

One ViewStat per HVAC system.

Mount on an interior wall.

In a room frequently occupied.

At least 18 inches (45.72 cm) from any outside wall.

Approximately 5 feet (1.52 m) above the floor. Check with local building codes for height requirements in commercial applications.

DO NOT locate the thermostat:

Behind doors, in corners or other dead air spaces.

In direct sunlight or near lamps, appliances or other sources of radiant heat.

On an outside wall or wall exposed to an unconditioned space (i.e. garage, etc.).

In the flow path of a supply register, in stairways or near outside doors.

On a wall where concealed pipes and/or duct work will affect the thermostat.

Near sources of electrical interference such as arcing relay contacts.

With remote temperature sensors

Follow the guidelines for placement of the sensors and locate the thermostat indoors where operating range (see specs) will not be violated (i.e. do not install in a cold garage or hot equipment room). See the Support Module Installation and Wiring section on page 33 for details.
