Maxitrol T115 Stat

For veteran contractors managing precise climate control, the Maxitrol T115 Room Override Thermostat is a critical field-proven component designed to integrate with Selectra Series 14, 21, 31, and 94 electronic gas modulation systems. This room override stat provides a dedicated interface to adjust space temperatures between 40°F and 90°F, effectively signaling the modulation amplifier to transition to high fire when the ambient temperature falls below your target setpoint. Engineered for use with the TD121 Remote Temperature Selector, the T115 is ideal for commercial makeup air units and industrial space heating where maintaining a tight discharge air temperature is non-negotiable for system efficiency and occupant comfort.

When performing a Maxitrol thermostat installation, ensure the unit is placed in a neutral area to sense true average room temperature, avoiding the direct path of discharge air. The T115 utilizes low-voltage 24V AC power and works in tandem with Maxitrol modulating gas valves to eliminate the temperature swings commonly associated with standard on/off cycles. By providing high-precision temperature control, this override stat minimizes energy wastage and maximizes the performance of indirect fired heaters and makeup air systems. Its rugged construction and factory calibration make it a reliable choice for technical crews looking for a "set and forget" solution in demanding HVACR environments.

• Seamless Compatibility: Specifically designed to match Selectra Series modulation systems and MR series valves.
• Precise Range: Accurate setpoint adjustment from 40°F to 90°F for versatile climate control.
• Optimized Efficiency: Triggers high-fire mode only when necessary to reduce fuel consumption and equipment wear.
• Modular Design: Functions as a dedicated room override in complex multi-component sensing circuits.

• How does the T115 interface with the Selectra amplifier? It connects via the remote selector circuit to provide a space-sensing signal that overrides the primary duct sensor when the room temperature drops.
• Can this be used as a standalone thermostat? No, the T115 must be used in conjunction with a Maxitrol remote temperature selector (like the TD121) for proper system operation.
• What is the proper wiring for multiple furnace applications? In multi-furnace Series 30 or 31 setups, the override stat typically wires into the Master unit amplifier to control the entire bank.
