Honeywell M4185B1058 Modutrol IV Motor

The Honeywell T7300A1005 thermostat is a multistage control unit designed for both conventional and heat pump systems, operating at 24VAC with a 50/60Hz frequency. It provides precise temperature regulation, ensuring comfort and efficiency in various HVAC applications. This thermostat includes a transformer and requires a subbase for installation. The device is ideal for managing complex heating and cooling configurations, offering reliable and accurate control. Its robust design and the inclusion of the trusted Honeywell logo ensure long-lasting performance and dependability. The T7300A1005 is a preferred choice for residential and commercial settings, providing optimal energy management and comfort through its advanced multistage capabilities. This thermostat effectively integrates with Series 41 and Series 81 Modutrol IV motors, which are 2-position spring-return motors used to operate dampers or valves, ensuring the controlled element returns to the starting position during power interruptions.

Features

• Fixed torque throughout the entire voltage range.
• Integral spring return returns motor to normal position when power is interrupted.
• Integral junction box provides NEMA 3 weather protection if motor is mounted in the upright position.
• Motor and circuitry operate from 24 Vac.
• Quick-connect terminals are standard–screw terminal adapter is available.
• Adapter bracket for matching shaft height of older motors is available.
• Motors have field adjustable stroke (90 to 160 degrees).
• Motors are designed for either normally open or normally closed valves and dampers.
• Integral auxiliary switches are available factory mounted, or can be field added.
• Motors can operate valve linkages from the power end or auxiliary end shafts for normally closed or normally open valve applications.
• All models have dual shafts (slotted and tapped on both ends).
