The D1-TMP Digital Day/Night temperature controller is a very accurate device that allows the user to control EITHER a cooling or heating device.
A two meter long water-proof remote temperature sensor can be placed where it can sense the water or air temperature that the D1-TMP will be controlling.
The user first selects whether they are controlling a cooling or a heating device.
Feature with Day and Night temperature settings, as well as the dead band (hysteresis). Separate Day and Night settings are critical in order to maintain proper temperatures during periods of light and darkness.
Works by measuring the temperature and switching ON or OFF the device connected to the D1-TMP when the temperature is at the user’s desired setpoint.
A built-in photocell automatically senses whether it is light of dark and will activate the correct user’s setpoint.
