Installation
Physical Dimensions
Choose the placement of the control early in the construction process to enable proper wiring during rough-in.
• Keep the control dry. Avoid potential leakage onto the control.
• Maintain relative humidity less than 90% in a non-condensing environment.
• Avoid exposure to extreme temperatures beyond 32-122°F (0-50°C).
• Install away from equipment, appliances, or other sources of electrical interference.
• Install to allow easy access for wiring, viewing, and adjusting the display screen.
• Install approximately 5 feet (1.5 m) off the finished floor.
• Locate the control near pumps and/or zone valves if possible.
• Provide a solid backing which the enclosure can be mounted to. Example: plywood or wall studs.
• Use the conduit knockouts provided on the upper, lower, back and sides of the enclosure for wiring.
