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 applications.
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

Installation
Digital Setpoint Control II (17029)
Watertight Sensor (17031)
For proper control, the sensor for
the setpoint control must be located
within the heating and or cooling slab.
The sensor should be placed midway
between rows of tubing, and should be
placed in conduit which is cast into the
slab, so that replacement is possible.

Wiring
Sensor A is triggering the two relays,
Relay 1 being boiler circulator pump,
and Relay 2 being system circulator
pump. In heating mode, when the
sensor detects temperature lower than
the selected setpoint minus the selected
differential both relays will be energized.
When the temperature reaches the
setpoint the relays will de-energize.
Note:
If using 24V to power the controller,
the 24V supply must be connected to
terminals that are marked +, C on the
left side of the control.
If using 120 or 240V to power the
controller the 120 or 240V supply must
be connect to corresponding terminals
clearly marked on the right side of the
control. When connecting the sensor
connect both red wires to one terminal
and the white wire to the other terminal.
Terminals for sensor marked "T".

Programming
Once the control is powered on press "MENU" button on
the control keypad to adjust settings:
At any point during the programming you may press the
"HOME" button to return back to the sensor viewing.
1. Press "MENU", then press the right arrow button when
the "Program Screen" appears
2. When the "Relay Screen" appears, press right arrow
to select Relay 1
3. Scroll up or down to select "Setpoint 1" then press the
right arrow button
4. Using the up and down arrows to adjust the Setpoint 1
desired setpoint -40 - 248 °F (this is the maximum slab
temperature setting of the heating and or cooling system)
5. Once the setpoint has been adjusted press the right
arrow button to accept and to display the "Relay 1" menu
6. Select "Diffrntl" by pressing the right arrow button
7. Using the up and down arrows, adjust the differential,
the range is 1 - 150°F, once selected press the right
arrow to accept and return to "Relay 1" menu
8. Select "Sensor A or Sensor B" for "Relay 1" using the up
and down arrows, then press right arrow button to accept
9. Select "Heat / Cool" option for "Relay 1" then press
right arrow button
10. Once you have completed all of the steps either press
the "HOME" key or scroll down using the down arrow
to "EXIT" and then press the right arrow button
11. Repeat all steps to congure "Relay 2"
Once all programming is complete the conguration can
be locked to prevent any unauthorized changes.
To Lock or Unlock the keypad simply press and hold
the "MENU" and "HOME" buttons simultaneously for
ve seconds.
Operation
Heating Mode
In heating mode once the slab temperature reaches
the selected setpoint temperature the relay will be de-
energized. As the slab temperature decreases below the
selected differential the relay will energize.
Example: Slab setpoint is set to 85 °F differential is set to
5, once the slab temperature is below
80 °F the relay will be energized.
Cooling Mode
In cooling mode, the differential is above the setpoint. So
as the temperature rises higher than the selected setpoint
plus the differential the relay is energized.
Example: Slab temperature is set to 66 °F with a
differential of 2. When the slab temperature reaches 68 °F
the relay will be energized.

Troubleshooting
If the system is not operating correctly, rst check that all
electrical connections have been made properly. Check
for power to all components (120 V and 24 V).
If the setpoint conguration is correct disconnect the
sensor and check its resistance. Replace the sensor if its
resistance value does not match the temperature in the
accompanying chart to the right.
