The Maxitrol TD244A Space Temperature Selector is a critical component for Selectra Series 44 electronic gas flame modulation systems, specifically engineered for direct-fired makeup air units and space heating applications. This wall-mounted interface allows for precise environmental control, featuring a 40°F to 80°F temperature range. It functions as a remote setpoint adjuster, communicating with a Selectra amplifier to modulate gas flow through M/MR series valves. By replacing a standard Selectrastat, the TD244A offers a centralized control point, ideal for maintaining stable ambient conditions in industrial facilities or commercial warehouses. Technical crews should note that this selector must be paired with a space temperature sensor of the same 40-80°F range to ensure proper signal scaling and system calibration. Its integral selector dial provides a responsive adjustment interface, eliminating the lag associated with traditional mechanical thermostats or butterfly valve assemblies. Key Benefits Precise Modulation: Facilitates instantaneous gas flow adjustments for stable temperature maintenance in direct-fired equipment. Selectra Compatibility: Designed to integrate seamlessly with Series 44 amplifiers and modulating-regulating valves. HVAC Efficiency: Replaces less efficient mod motors, reducing energy consumption through accurate electronic gas modulation. Contractor-Grade Durability: Features a robust housing suitable for wall mounting in high-traffic industrial environments. Common Questions What systems are compatible with the TD244A? The TD244A is specifically designed for Selectra Series 44 systems used in space heating and makeup air applications. It is typically used in conjunction with an A1044 amplifier and must match the temperature range of the installed sensor. Is this a standalone thermostat? No, this is a temperature selector. It requires a compatible remote sensor and an electronic amplifier to function as a complete modulation control circuit. Can I use this for discharge air control? While Series 44 units can manage discharge air, the TD244A is primary for space temperature sensing. For discharge-only control, verify the specific wiring configuration of your Selectra system.
