Blocked Vent Switch
This heater is equipped with a blocked vent pressure
switch to prevent the operation of the heater when too
much of the vent is blocked. This switch is located on the
right side of the heater near the front. See Figure 2.
Figure 53. Blocked Vent Switch
Condensate Switch
The condensate switch is located lower rear (right corner)
of the heater. See Figure 3. Remove the lower access
panel to access the condensate switch. The switch will
shut the unit down in the event of excessive condensate in
the condensate compartment of the heat exchanger.

Flow Meter (Optional)
The heater is equipped with a flow meter which measures
flow through the heater and the control adjusts firing rate
based on flow. See Figure 1.

Vent Temp Sensor
The heater is equipped with a vent temperature sensor.
Upon initial installation/comissioning of the heater, the
vent material used for installation (PVC, CPVC, PP, or SS)
must be entered into the control. See Figure 4. The factory
default value is "PVC".
The control uses the input from this sensor to automatically
reduce firing rate should the vent temperature approach
the vent material temperature limits.

User Interface

The touchscreen user interface uses a high definition
4.3" (109 mm) capacitive screen. It includes an extensive
graphical library used to represent different pipe
configurations, error location, and operation of the unit.
The touchscreen menu bar becomes visible at the bottom
of the screen allowing navigation through additional icons
(View, Adjust, Boiler, Tools, Document Viewer and Wi-Fi).
For detailed descriptions of the various screens, page
flows and basic instructions, consult the Touchscreen
Quick Start User Guide (5000.74) and VERSA IC Manual
(5000.72).
If your unit has Raymote installed, refer to the Raymote
installation and operation manual (5000.721).
