Contemporary Controls PVI Industries TempTrac water heater control via BASgatewayLX BACnet points list

Updated 12 November 2026

Short answer

Gateway profile for the PVI TempTrac: 123 objects (106 AI, 17 BI), all polled. Most analog inputs are the control's parameters (setpoints 1-5, differentials, limits, delays, outdoor reset and weekly setback); the live values are the three probe temperatures and states, the 4-20 mA modulation output, relay states and alarm bits.

This page lists 123 BACnet objects for the Contemporary Controls PVI Industries TempTrac water heater control via BASgatewayLX — 0 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Contemporary Controls’s own free documentation, linked below.

BMS integration notes: Contemporary Controls PVI Industries TempTrac water heater control via BASgatewayLX

Integration in brief

Read probe 1 temperature against set point 1, the modulation output and relay 1, and watch the alarm bits. Every object is read-only.

Minimum points to map

The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

Integration notes

Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the PVI Industries TempTrac water heater control via BASgatewayLX and exports what it actually has to Excel — free.

Questions about the Contemporary Controls PVI Industries TempTrac water heater control via BASgatewayLX

How many BACnet points does the Contemporary Controls PVI Industries TempTrac water heater control via BASgatewayLX have?

This list has 123 BACnet objects: 106 analog inputs, 17 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Contemporary Controls PVI Industries TempTrac water heater control via BASgatewayLX BACnet points are writable?

None of the listed objects are marked writable in the source documentation. The source has no read/write column, so this is inferred from object type.

Where is the official Contemporary Controls PVI Industries TempTrac water heater control via BASgatewayLX BACnet documentation?

The source is BASgatewayLX Modbus device profile PVI_Industries_TempTrac_Water_Heater_a (PVI_Ind_TempTrac_Water_Heater_a_LX.csv), published free by Contemporary Controls at https://www.ccontrols.com/support/dp/PVI_Ind_TempTrac_Water_Heater.zip.

What are the minimum BACnet points to integrate the Contemporary Controls PVI Industries TempTrac water heater control via BASgatewayLX?

Start with AI 100 Probe 1 temperature (Probe 1 (tank) temperature); AI 1 Set point1 (Set point 1); AI 106 Modulation rate output (4 to 20mA) (Modulation output, %); BI 107 Status of Relay 1 (Relay 1 (heat) on); BI 114 High Temperature Alarm beep Flash yellow HA=2 (High temperature alarm); BI 113 Low Temperature Alarm beep Flash Yellow LA= 1 (Low temperature alarm); BI 115 Probe 1 error open or shorted Drops call for (Probe 1 error); BI 118 ALARM 1 (stops heating) Input 1 (Alarm 1 (input 1, stops heating)).

How do I check these points on the real PVI Industries TempTrac water heater control via BASgatewayLX?

Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
