Electronic Temperature Control with Remote Bulb Sensor (AC) — Heating or Cooling, Adjustable
The Electronic Temperature Control & Bulb Well Assembly (AC) provides accurate, adjustable temperature control for cooling (or heating) systems, pairing electronic precision with remote-sensing capability. It’s used to switch a fan, pump, or other device based on fluid temperature — for example, cycling a cooler’s AC fan to hold a target oil temperature.
The control operates in either heating or cooling mode with an adjustable differential, so you can tune both the set point and the on/off spread to your application. Its interchangeable temperature sensor mounts remotely (via the included bulb well) to read fluid temperature away from the control itself, and the line-voltage, single-stage design provides a single-pole, double-throw (SPDT) relay output with LED status indication for straightforward integration.
Housed in a NEMA 1 high-impact plastic enclosure, it mounts on a surface or DIN rail for flexible panel or field installation. It’s well suited to controlling AC-fan-driven TTP coolers (AO, AOC, AOF, AOVH) where adjustable, more precise temperature control is needed than a fixed single-set-point switch provides. TTP Application Engineering can help configure it for your system.

Frequently Asked Questions
It’s an adjustable, line-voltage electronic temperature control from Thermal Transfer Products with a remote bulb sensor, used to switch a fan or other device based on fluid temperature — for example, controlling an AC cooler fan to hold a target oil temperature.
Yes — it has selectable heating or cooling modes of operation, with an adjustable differential to set the on/off temperature spread.
The interchangeable temperature sensor mounts remotely (in the supplied bulb well) so it can read fluid temperature at the cooler or line, away from the control enclosure. Being interchangeable, the sensor can be replaced or swapped without changing the whole control.
A single-pole, double-throw (SPDT) relay output with LED indication, on a line-voltage single-stage control.
In a NEMA 1 high-impact plastic enclosure suitable for surface or DIN-rail mounting.
The Single Set Point Switch is a simple fixed on/off switch. The MAGHEX 2 is a programmable controller for DC fan systems. This electronic control is an adjustable, line-voltage (AC) control with heating/cooling modes, adjustable differential, remote sensing, and a relay output — the most flexible of the three for AC-powered cooling systems.
