11 TEMPTRAC™ ELECTRONIC CONTROLLER PANEL

11.1Principle Of Operation

The water heater operates to satisfy the setpoint of the TempTrac digital control whose sensor is located near the top of the water heater tank. Demand (flow) will typically create a drop in temperature, thus activating the water heater to add heat to the stored water. This setpoint is the desired water temperature to maintain.

11.2Lower LED Readout

The default display of the lower readout (Probe 1) is the stored water temperature sensed near the top of the water heater tank. This is used to regulate the temperature of the water heater.

11.3Upper LED Readout

The default display of this readout will display “nu”. This readout can display a temperature reading from a 2nd probe. The 2nd probe can be installed in a thermal well (this optional probe and thermal well, with heat conductive paste, is custom and must be ordered from your PVI representative or directly from PVI) to remotely monitor water temperatures, such as blended water temperature, downstream of a thermal mixing valve or a remote storage tank. Both Probe 1 and Probe 2 temperatures are available for monitoring through the optional MODBUS RTU interface.

11.4Control Buttons

SET

Displays and modifies the temperature set points.

In programming mode, it selects a parameter or confirms an operation.

 

UP

Displays and modifies the energy saving (Night Time setback) settings.

In programming mode, it browses the parameter codes or increases a displayed value.

 

 

 

DOWN

Displays the working hours of the load relays.

In programming mode, it browses the parameter codes or decreases a displayed value.

 

CLOCK

Changes lower display from the stored water temperature to current time and day.

 

 

 

Changes upper display from Probe 2 temperature to Probe 3 temperature (when installed).

EXT

Also displays the temperature difference of the stored water temperature minus Probe 2

 

temperature. In programming mode it sets the 4-20mA output (password is required).

ON/OFF

Switches the control ON or OFF.
