When the Basic Heating Control is powered up, the control displays
the control type number in the LCD for two seconds. Next, the software
version is displayed for two seconds. Finally, the control enters into the
normal operating mode.
The Basic Heating Control uses a floating action that can control Viega
diverting or mixing valves to vary the supply water temperature to a
hydronic system. The supply water temperature is based on the outdoor
temperature.
The maximum water temperature setting in the Basic Heating Control
should not be used as a safety high limit control. To protect floors from
high water temperatures in case of main control failure or removal, make
sure high limit is set on mixing device.
