Universal Thermostat Heating Only – #DT90A1008

Extra-Large Backlit Display
The DT90 display features large characters and high contrast screen, important for those with impaired vision.

Simple Interface
The user interface has been made as simple as possible to make DT90 very easy to use.

Off/Standby Button
The off/standby button allows DT90 to switch off the heating system at the touch of a button.

Installer Mode
The Installer Mode is where DT90 can be configured for different applications, and customized to meet the needs of the user.

NVRAM Storage of Settings
All parameter settings are stored in a special kind of memory called
NVRAM so they will be retained indefinitely even if the batteries are
removed.

Advanced Self-learning TPI Control
DT90 uses a self-learning ‘fuzzy logic’ time-proportional control
algorithm. This form of control is better than conventional PI control
as it has a faster response and better performance in steady-state
conditions, ensuring significant energy savings.
