About ICM

ICM Controls is a manufacturer of electronic controls for heating, ventilation, air conditioning, and refrigeration (HVACR) equipment. The company was founded in 1977 and is headquartered in Syracuse, New York. ICM's product line includes ignition transformers, furnace control boards, line voltage monitors, time-delay relays, fan speed controls, and thermostats. These components are used in residential and commercial HVAC systems, boilers, and refrigeration units. 3G Electric supplies ICM products globally, serving plant engineers, maintenance managers, and procurement specialists who require reliable replacement parts and controls for industrial and commercial equipment.

ICM's product families cover several key application categories. Ignition transformers, such as the ICM1501, generate high-voltage sparks to ignite oil in hot water and steam boiler burners. They are bracket-mounted and compatible with specific OEM models like R8184G4066. Furnace control boards, including the ICM292A and ICM282B, are integrated controls that manage inducer operation or humidifiers in gas furnaces. These boards are designed as OEM replacements for brands such as Rheem and Carrier, with specific voltage inputs and outputs. Line voltage monitors, like the ICM492D, detect voltage unbalance and feature LCD displays with SPDT contact forms. Time-delay relays, such as the ICM206B, provide adjustable off-delay functionality. Fan speed controls, including the ICM325A, are refrigerant-actuated and regulate fan speed based on pressure and temperature inputs. Temporary construction thermostats, like the ACH065 and ACH060, are cylindrical on-off devices for heat-only applications.

Technical buyers should note that ICM controls are specified with precise operating parameters. For example, the ICM325A fan speed control operates from 310 to 350 psi and accepts 120 to 600V AC input with a 10 A output. The ICM492D line voltage monitor handles 18V AC to 240V AC and offers an adjustable percentage volts unbalance range from 5 to 25%. The ICM206B time-delay relay operates on 18 to 30V AC and has a knob-adjustable delay range of 3 to 10 minutes. These specifications allow engineers to match controls to specific system requirements. ICM products are designed for integration into existing equipment, often as direct replacements for OEM parts. 3G Electric supports the ICM line by stocking a range of these controls and providing global shipping. Our team can assist with part number cross-referencing and technical inquiries to ensure the correct component is selected for the application. We do not manufacture these products; we distribute them as part of our broader portfolio of industrial equipment and controls.

Common Applications

  • Commercial refrigeration — ICM325A refrigerant actuated fan speed control for maintaining precise temperature and pressure in condenser units.
  • Residential heating — ICM1501 ignition transformer for oil-fired hot water and steam boiler burners.
  • HVAC service — ICM292A integrated furnace control board for Rheem gas furnaces, controlling inducer operation.
  • Industrial voltage protection — ICM492D line voltage monitor for detecting voltage unbalance in single-phase systems.
  • Building automation — ICM206B time-delay relay for off-delay control of fans or compressors in HVAC equipment.
  • Construction heating — ACH065 or ACH060 temporary construction thermostats for heat-only applications on job sites.

Frequently asked questions

Common questions about ICM from 3G Electric.

What is the operating range of the ICM325A refrigerant actuated fan speed control?

The ICM325A operates within a pressure range of 310 to 350 psi. It accepts an input voltage of 120 to 600V AC and delivers a 10 A output. The control includes two pressure sensors and two temperature sensors, which allow it to modulate fan speed based on refrigerant conditions. This makes it suitable for refrigeration systems where precise fan control is needed to maintain optimal temperatures and pressures. The ICM325A is a direct replacement for many OEM fan speed controls and is available from 3G Electric.

Which furnace models are compatible with the ICM292A integrated furnace control board?

The ICM292A is designed as an OEM replacement for Rheem furnace models. It is compatible with part number 62-24140-04. This control board operates on 115V AC and controls inducer operation in gas furnaces. It is an integrated control, meaning it combines multiple functions into a single board. When replacing a furnace control board, it is important to verify the part number and compatibility with the specific furnace model. The ICM292A is available from 3G Electric and can be cross-referenced with the original Rheem part number.

What is the voltage monitoring range of the ICM492D line voltage monitor?

The ICM492D monitors single-phase line voltage from 18V AC to 240V AC. It features an LCD display and a SPDT (Single Pole Double Throw) NO/NC contact form. The adjustable percentage volts unbalance range is from 5 to 25%. This allows users to set the threshold for voltage unbalance detection. The ICM492D is used to protect equipment from voltage imbalances that can cause overheating or premature failure. It is suitable for a variety of HVAC and refrigeration applications and is supplied by 3G Electric.

What is the delay range of the ICM206B adjustable time-delay relay?

The ICM206B is an adjustable time-delay relay configured as a delay on break (off delay) type. It has a knob-adjustable delay range of 3 to 10 minutes. The relay operates on 18 to 30V AC and is rated at 1.5 A. It has 4 pins and is surface-mounted. This relay is used in applications where a delay is needed after a control signal is removed, such as in fan control or compressor protection. The ICM206B is available from 3G Electric.

What are the specifications of the ICM1501 ignition transformer?

The ICM1501 is an oil-fuel ignition transformer designed for hot water and steam boiler burners. It generates a high-voltage spark to ignite oil. It features bracket mounting and is compatible with model R8184G4066. The transformer is also compatible with R8184G1161 and R8184G1294. It is a direct replacement for many OEM ignition transformers. The ICM1501 is used in boiler systems where reliable ignition is critical. 3G Electric supplies this transformer globally.

What is the control point of the ACH065 temporary construction thermostat?

The ACH065 is a cylindrical on-off thermostat for temporary heat-only applications. It operates on 18 to 30V AC and has a control point of 65°F with a 9°F differential. It features universal mounting direction, allowing flexible installation. This thermostat is typically used in construction sites for temporary heating. It is a low-voltage device and is not programmable. The ACH065 is available from 3G Electric, along with the ACH060 model, which has a 60°F control point.
