TURBOPOWER 99WATER HEATER

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 the upper readout (Probe 3) is the flue gas temperature exiting the heater. This readout may also display a temperature reading from Probe 2. Probe 2 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. All the probes temperatures are available for monitoring through the optional MODBUS RTU interface.

settings.

 

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

DOWN

When held for 3 seconds, 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. When held for 3 seconds, will put you in manual mode for setting 4-20mA

 

 

output used in startup (password is required).

 

 

ON/OFF

Switches the control ON or OFF. The BAS can still monitor the probe temperatures.

Appliance will not heat when in the off-state.
