Maxitrol TD92-0509 Temperature Selector

The Maxitrol TD92-0509 Temperature Selector is a professional-grade remote temperature dial engineered for the Selectra Series 92 electronic gas modulation system. This component provides a precise setpoint range of 50°F to 90°F (10°C to 32.2°C), serving as a reliable control interface for indirect fired furnaces and makeup air heaters. Unlike standard residential thermostats, this industrial temperature controller utilizes a 6-place terminal block for robust field wiring and is designed to communicate with A1092 or A1192 amplifiers. By enabling continuous modulating gas valve adjustments, it eliminates the inefficiencies of traditional on/off cycling, maintaining stable discharge air temperatures in demanding commercial environments. The TD92-0509 is the preferred HVAC control part for technicians looking to upgrade manual butterfly valves or high-maintenance mod motors with a streamlined, analog solution that supports wire lengths up to 300 feet for flexible remote mounting.

• Precise Modulation: Facilitates seamless burner pressure adjustment when paired with M/MR series valves.
• Extended Installation Range: Supports a maximum wire length of 300 ft, allowing for versatile placement in large facilities.
• Enhanced Compatibility: Specifically designed for Series 92 systems using standard 4-wire connections instead of ribbon cables.
• Industrial Durability: Specifically calibrated for natural gas and LP gas mixture piping systems in commercial applications.

What is the difference between the TD92-0509 and the TD94 series?
The TD92-0509 features a manual analog dial for settings, whereas the TD94 series typically includes a digital readout. Both serve the same primary function within their respective Selectra systems.

Can this selector be used with a room override thermostat?
Yes, it is compatible with an optional T115 room override thermostat to allow space temperature control to influence the discharge air setpoint.

What type of sensor is required for this system?
This selector is typically used in conjunction with a 1,000 ohm RTD sensor, such as the TS194Q or TS394, to monitor discharge air temperatures.
