Ventamatic XXFIRESTAT Thermostat User Manual

Product Overview

The Ventamatic XXFIRESTAT is a 10-Amp adjustable programmable thermostat designed for use with power attic ventilators. It features a built-in Firestat safety mechanism that automatically shuts off the fan at 183°F (83.9°C) to prevent overheating. This thermostat promotes energy-efficient operation by controlling attic ventilators to equalize indoor and outdoor temperatures, helping to maintain a comfortable environment and reduce energy consumption. It is suitable for controlling up to three units, not exceeding a total of 10 amps.

• Firestat Safety Feature: Automatically shuts off the fan at 183°F (83.9°C) for enhanced safety.
• Adjustable Temperature Range: Allows setting the fan's operation between 50°F (10°C) and 120°F (49°C).
• Energy-Efficient Operation: Optimizes power attic ventilator use to balance attic temperatures.
• Bi-Metallic Switch: Features an adjustable bi-metallic switch for reliable temperature sensing.
• Capacity: Controls up to three units, with a maximum combined load of 10 amps.

Safety Information

Always prioritize safety during installation and operation. This device is automatically started. To reduce the risk of injury, disconnect from the power supply before servicing. Do not use this fan with any solid-state speed control device. This thermostat is intended for residential use only.

Installation and Setup

The Ventamatic XXFIRESTAT thermostat is designed for straightforward installation. It should be mounted in a location where it can accurately sense the attic temperature, away from direct sunlight or drafts that could affect its readings.

Mounting

The thermostat unit measures approximately 4.8"D x 2.5"W x 4.8"H and weighs about 0.35 pounds. It is designed for easy mounting, typically on a wall or beam within the attic space. Ensure the mounting surface is stable and secure.

Wiring Instructions

Before wiring, ensure all power to the attic ventilator circuit is disconnected at the main breaker. The thermostat controls power attic ventilators by interrupting the 120V power supply. The wiring diagram is clearly printed on the front of the unit. You will need to remove the cover to access the wiring terminals.

• Connect the 120V, 60 Hz power supply to the designated "Power Supply" terminals.
• Connect the wires leading to the attic fan motor to the "To Motor" terminals.
• Ensure proper grounding as indicated in the diagram.
• The Firestat is an internal safety feature and does not require separate wiring.

It is recommended to consult a qualified electrician if you are unsure about any wiring procedures.

Operating Instructions

The Ventamatic XXFIRESTAT thermostat is designed for simple, automatic operation once installed and configured.

Setting the Temperature

The thermostat features an adjustable dial on its front face, allowing you to set the desired temperature range for fan operation. The temperature range is from 50°F (10°C) to 120°F (49°C). Use a small screwdriver to carefully rotate the dial to your preferred temperature setting. The fan will turn on when the attic temperature rises above this set point and turn off when the temperature drops below it.

Firestat Functionality

In addition to temperature control, the thermostat includes a Firestat safety feature. This mechanism is designed to automatically shut off the attic fan if the temperature in the attic reaches 183°F (83.9°C). This is a critical safety measure to prevent the fan from exacerbating a fire condition by drawing in oxygen. The Firestat operates independently of the adjustable temperature setting and is a non-resettable safety cutoff.

Maintenance

The Ventamatic XXFIRESTAT thermostat requires minimal maintenance. Periodically inspect the unit for any visible damage, loose connections, or accumulation of dust and debris. Ensure the area around the thermostat is clear to allow for accurate temperature sensing. Before any inspection or cleaning, always disconnect power to the unit at the circuit breaker.

• Cleaning: Gently wipe the exterior of the thermostat with a dry, soft cloth. Do not use liquid cleaners or solvents.
• Connection Check: Annually, or if issues arise, verify that all electrical connections are secure and free from corrosion.
