Tandem Control IQ Pump

Control-IQ Technology

The easy choice for ages 6 and up to help protect from highs and lows.

Trying to keep your blood sugar in range can be stressful and time-consuming. Our Control-IQ advanced hybrid closed-loop technology makes it easier by predicting and helping to prevent highs and lows.


Control-IQ™ technology automatically adjusts insulin levels based on Dexcom G6 continuous glucose monitoring (CGM) readings.*


Control-IQ technology can also deliver automatic correction boluses (up to one an hour) to help prevent hyperglycemia.


Control-IQ technology includes optional settings for Sleep and Exercise that adjust range of treatment values for more control.

How it works

The t:slim X2 insulin pump with Control‑IQ technology is designed to help increase time in range (70-180 mg/dL) using Dexcom G6 CGM values to predict glucose levels 30 minutes ahead and adjust insulin delivery accordingly.


Icons display on the pump screen to visually indicate when insulin delivery is increasing, decreasing, or stopped. Please refer to the table for a breakdown of status icons

Easy to use. Easy to love.

We understand that you want your kid to enjoy all the wonderful parts of growing up, instead of being burdened by constantly worrying about their diabetes. The t:slim X2 insulin pump with Control-IQ technology operates in the background without needing constant input or interaction, so your kid can be a kid.

Connect at a glance

The t:connect® mobile app serves as a discreet secondary display for your t:slim X2 insulin pump, so you can stay informed of your diabetes management from the convenience of your phone. View your pump data, including basal and bolus insulin events, insulin on board, carbs, settings, and both pump and sensor status.§

Zero Fingersticks

Dexcom G6 CGM integration with the t:slim X2 pump provides exceptional accuracy3 for optimized insulin delivery. Dexcom G6 is the first real-time, integrated continuous glucose monitoring (iCGM) system requiring zero fingersticks for calibration or mealtime dosing.^

^ If your glucose alerts and readings from the G6 do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions.

Responsible Use of Control‑IQ Technology

Even with advanced systems such as the t:slim X2 insulin pump with Control-IQ technology, you are still responsible for actively managing your diabetes. Control-IQ technology does not prevent all high and low blood glucose events. The system is designed to help reduce glucose variability, but it requires your accurate input of information, such as meals and periods of sleep or exercise. Control-IQ technology will not function as intended unless you use all system components, including your CGM, infusion sets and pump cartridges, as instructed. Importantly, the system cannot adjust your insulin dosing if the pump is not receiving CGM readings. Since there are situations and emergencies that the system may not be capable of identifying or addressing, always pay attention to your symptoms and treat according to your healthcare provider’s recommendations.

* Dexcom CGM sold separately. Transmitter can only be paired with one medical device (either a Dexcom receiver or t:slim X2 insulin pump) and one consumer device (phone or tablet) at the same time.
† If glucose values are predicted to be above 180 mg/dL, Control-IQ technology calculates a correction bolus using the Personal Profile settings and a target of 110 mg/dL and delivers 60% of that value. An Automatic Correction Bolus will not occur within 60 minutes of a bolus that has been delivered or cancelled.
‡ As measured by CGM.
§ The information on the t:connect mobile app display may not be identical to the current status of your pump. Wireless uploads from the t:connect mobile app to the cloud-based t:connect web application require a compatible phone and an internet or wireless data connection. Uploads to the t:connect web application do not take place in real time and should not be relied upon by healthcare providers or caregivers for remote patient monitoring. Standard carrier data rates may apply.
