Applications

The Viega Basic Digital Setpoint Control II is a 
general purpose temperature control with a wide 
range of applications in the HVAC industry. This 
control provides two isolated SPDT relay contacts.
The two relays are controlled by a watertight sensor, 
included with the Basic Digital Setpoint Control. 
This control is commonly used as basic heating 
and/ or cooling system control for commercial 
and residential slab application.  

Features

• Setpoint Control for Heating and Cooling
• Simple installation and programming
• Large digital LCD display
• Reliable, economical
• Two relay outputs with individual
  Setpoint capability
• Watertight Sensor included
