Manufactured by ICM Controls. Review: used to prevent short cycling AC - Our ac system constantly trips the freeze stat due to poor design and install by previous owners. Short of replacing an expensive newer system or throwing more money at supposed fixes I tried this to give the system plenty of time to equalize before cycling the compressor again. The new freeze stat was supposed to give more than a few minutes to reset but in reality it is two to three minutes. The thermostat was also supposed to prevent short cycling but it does not. To any hvac pros who might read this we have had five highly recommended companies out to service and troubleshoot at the expense of 2000$ with only modest results. I recommend this device. For us it has worked as intended. Review: Does it's 'job' well...just be careful. - Essential add-on to an A/C Unit for those hot & humid summer nights when the A/C cycles far to often for the 'health' of the compressor. Consider pre-assembling a simple jumper (Pic#1) to make the connection between the contactor-relay and the delay timer much easier & safer. If you have never worked around capacitors before, seriously consider getting someone who is familiar with this equipment to install it. Your compressor will thank you for the new timer. ## Features - ⚡𝗣𝗿𝗼 𝗦𝘂𝗽𝗽𝗹𝗶𝗲𝘀 𝗶𝘀 𝗮𝗻 𝗮𝘂𝘁𝗵𝗼𝗿𝗶𝘇𝗲𝗱 𝗱𝗶𝘀𝘁𝗿𝗶𝗯𝘂𝘁𝗼𝗿 𝘁𝗵𝗮𝘁 𝗵𝗼𝗻𝗼𝗿𝘀 𝗜𝗖𝗠 𝘄𝗮𝗿𝗿𝗮𝗻𝘁𝘆!' - ⚡𝗖𝗼𝗺𝗽𝗿𝗲𝘀𝘀𝗼𝗿 𝗣𝗿𝗼𝘁𝗲𝗰𝘁𝗶𝗼𝗻 - The ICM203 prevents damage from rapid short cycling with built in lockout safety, helping the ICM-203 protect your compressor from costly wear over time. - ⚡𝗔𝗱𝗷𝘂𝘀𝘁𝗮𝗯𝗹𝗲 𝗗𝗲𝗹𝗮𝘆 𝗳𝗼𝗿 𝗙𝗹𝗲𝘅𝗶𝗯𝗹𝗲 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 - Set a custom delay from 1.8 to 600 seconds with the ICM203B, giving you precise control to match the exact needs of your HVAC or refrigeration system. - ⚡𝗪𝗶𝗱𝗲 𝗩𝗼𝗹𝘁𝗮𝗴𝗲 𝗥𝗮𝗻𝗴𝗲 𝗳𝗼𝗿 𝗕𝗿𝗼𝗮𝗱 𝗖𝗼𝗺𝗽𝗮𝘁𝗶𝗯𝗶𝗹𝗶𝘁𝘆 - Operating on 18 to 240 VAC, the ICM 203 fits a wide range of HVAC and refrigeration applications, making the ICM 203 B a versatile choice across many systems. - ⚡𝗦𝗶𝗺𝗽𝗹𝗲 𝟮 𝗪𝗶𝗿𝗲 𝗜𝗻𝘀𝘁𝗮𝗹𝗹𝗮𝘁𝗶𝗼𝗻 - The ICM-203B features an easy 2 wire hookup for a quick, reliable setup, so the ICM203 installs fast whether you are servicing one unit or several. - ⚡𝗗𝘂𝗿𝗮𝗯𝗹𝗲 𝗮𝗻𝗱 𝗥𝗲𝗹𝗶𝗮𝗯𝗹𝗲 𝗦𝗼𝗹𝗶𝗱 𝗦𝘁𝗮𝘁𝗲 𝗗𝗲𝘀𝗶𝗴𝗻 - Built with solid state components, the ICM 253... — wait, the ICM203B delivers long lasting performance even in demanding environments, season after season. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000LDKB3W | | Best Sellers Rank | #184,472 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #37 in HVAC Controls | | Brand | ICM Controls | | Brand Name | ICM Controls | | Color | Multicolor | | Customer Reviews | 4.3 out of 5 stars 189 Reviews | | Included Components | Control | | Item Dimensions D x W x H | 2"D x 2"W x 1.25"H | | Item Weight | 1.6 ounces | | Manufacturer | ICM Controls | | Manufacturer Part Number | ICM203 | | Model Number | ICM203 | | Number of Items | 1 | | Number of settings | 1 | | Product Dimensions | 2"D x 2"W x 1.25"H | | Screen Size | 1.25 inches | | UPC | 800442000169 745332196778 | | Unit Count | 1 Count | ## Product Details - **Brand:** ICM Controls - **Color:** Multicolor - **Item Weight:** 1.6 ounces - **Number of settings:** 1 - **Product Dimensions:** 2"D x 2"W x 1.25"H ## Images ![ICM203 Delay on Break Timer | ICM203B Universal Voltage Anti Short Cycle Compressor Protection Relay | 18 to 240 VAC | Adjustable 1.8 to 600 Seconds | ICM 203 B - Image 1](https://m.media-amazon.com/images/I/619QARzc-oL.jpg) ## Questions & Answers **Q: I need a scenario to help me understand. Power is applied to the unit, its remains closed for a specified time then opens until power is cut again?** A: This timer begins counting when the power goes off. It will not close until the set time has run out. If the power has been removed for longer than the set time, it will close within about 2 seconds when power comes on. This also prevents some wear tear on thermostat contacts (if they are mechanical contacts) because the final closing (making of the circuit) occurs in the delay timer, not the thermostat. Once the power is interrupted for any reason, the ICM203 opens until the set time has run out. Hoping this helps. **Q: Is this a 12v unit suitable for automotive applications?** A: No, this unit is for alternating current (AC) use only. Automotive applications are always direct current (DC). **Q: Will this hold up to protect a full-size refrigerator compressor?** A: According to the ICM 203 manufactures sheet I have the max output rating is 1.5 amps. I'm going to say way too small for any refrigerator compressor's direct power. Maybe you can put this in another part of the circuit with lower current, like a relay or thermostat, that triggers the compressor to start. That is the way these are typically installed on air conditioners, where you put this in the low power circuit that closes the relay that starts the compressor. So if the relay circuit is delayed/open, then the compressor wont start until this device closes that circuit. **Q: What is a good delay setting for an outside A/C unit?** A: The answer of 5 minutes is not necessarily right. I can guess that's the setting used by pros to avoid callbacks.Assuming the problem is tripping of the Condenser breaker, then the solution is to allow the head - high side - pressure to bleed down enough to equalize the system. Setting for 5 minutes, when 30 seconds to one minute would be enough, can be very much a nuisance. If the circulation blower runs immediately on restoration of house power, then 1 minute should be enough. Here's a way to tell without gauges - go to the inside coil location, with condenser running, listen to the hiss or gurgle where the tubing goes into the housing. Shut the power off to the furnace or air handler and see how long it takes for the sound to stop. Add 15 - 30 seconds to that and that is where to set the timer. The setting of course will not be all that accurate.Test by turning off the same furnace / air handler switch or breaker for 3 -5 seconds, then on, to see if the condenser breaker still trips. ## Customer Reviews ### ⭐⭐⭐⭐⭐ used to prevent short cycling AC *by J***S on July 4, 2024* Our ac system constantly trips the freeze stat due to poor design and install by previous owners.

I turned on the AC and let it run for 5 minutes, then I pulled the breakers to look like I lost power. Then I turned back on quickly. Looking at my Nest Thermostat on my phone and standing outside, the Nest turned Blue that it was cooling. But the compressor did not come on. After 6 minutes which is the setting I used, the compressor started up. So it works as designed and it will save my compressor from all the power outages I have been experiencing.
