ST – 280 Instructions manual
I. Use
The ST-280 universal room thermostat is designed to control and
monitor room temperatures and temperatures in central heating and
hot water systems. Additionally, the device can run a weekly heating
program and be operated with four mixing valves (using ST-61 control
modules). The device features an alarm clock, many useful settings and
a parental lock to protect against unwanted changes to settings. By
using the thermostat you will be able to comfortably control the
temperature in your home (central heating system) and the
temperature of hot water directly from your flat/house without having
to walk down to the furnace room.
An easy to read large graphic display with a backlit touch screen
makes it easy to read and change thermostat parameters. Other
advantages of the thermostat include a design that makes it easy to
mount the device on the wall, attractive appearance and reasonable
pricing.
The ST-280 room thermostat works with TECH’s RS
communications type controllers.
