TEMPERATURE CONTROLLER
WITH REAL-TIME CLOCK
GENERAL
The R7426A temperature controller covers all space, air or
water flow temperature applications within the selectable
control range of 0...50°C
(LOw range)
with optional high or low limit control and outside air
temperature compensation reset of the main setpoint. The
controller can be configured to perform space-discharge air
or supply water temperature cascade control.
FEATURES
Weekly time schedule with up to six switching points
per day
Automatic daylight saving time change
Four different operating modes: Comfort, Standby,
Night, and OFF
Yearly holiday programming in advance
Three types of holiday schedules
Self-adaptive optimum start program for room control
system
Night cycle program
Order Numbers
