Product description

WILLHI WH2408 TEMERPATURE CONTROLLER

Due to thermal inertia, the temperature may keep rising after heating stops. This is normal.

To reduce the overshoot, consider using a lower power heater or adjusting your setpoints accordingly.

no unnecessary complexity

REPLACEABLE PROBE, LONGER LIFE

The replaceable probe helps extend the product's lifespan by allowing

easy replacement

SET UP OF A DIFFERENT MODEL

Tired of flipping through the manual just to decode every setting? Try our WH2408 controller—intuitively designed for effortless setup in seconds!

EASY DIAL, SET IN SECONDS!

With the WH2408 controller, no complex parameters or confusing steps—just

quick, hassle-free setup

IN WHAT CASE SHOULD I USE TWO CONTROLLERS?

Scenario 1: Day-Night Temperature Fluctuations

For environments with signifcant day-night temperature changes use one WH2408 controller to manage a heating device (for instance, turn-on at 65°F , turn-off at 65.5°F) and another to control a cooling device ( for instance, turn-on at 80.5°F, turn-off at 80°F).

This setup ensures precise, energy-efficient control by activating devices only when the temperature moves outside the ideal range of 65°F to 80°F.

Scenario 2: Minimizing Temperature Overshoot

For applications requiring tighter temperature control, use one WH2408 to manage a heating device (for instance,turn-on at 90°F,turn-off at 95°F) and another to control a cooling device ( for instance, turn-on at 95°F, turn-off at 90°F).

This dual controller setup compensates for thermal inertia, ensuring the temperature quickly returns to the set range when overshooting occurs due to high device power.
