There are two main ways to reset a Tridium JACE 8000 running Niagara N4, depending on your goal. Reset the controller to factory-default configuration — removes the commissioned configuration and allows you to start again. Recover access to the controller — useful if...

What Does Nm Mean on a Valve Actuator?
Nm (Newton Metres) is the unit used to measure torque — the rotational force an actuator produces to operate a valve. In HVAC and Building Management Systems (BMS), selecting the correct actuator torque is essential for reliable valve operation. Why Is Torque...
What Does VA Mean on a Transformer?
VA (Volt-Amperes) measures a transformer's apparent power capacity. It tells you how much electrical load a transformer can safely supply. VA = Volts X Amps For example, a 24V transformer rated at 100VA can supply approximately 4.17A at 24V. Choosing the correct VA...
Kvs value – Calculation and meaning
Kvs value is the flow coefficient of a valve and indicates how much water can pass through it when the valve is fully open.
UPS (Uninterruptible Power Supply)
A UPS is commonly used with computers, servers, BMS controllers, network equipment, security systems and other electronic controls.
BMS Temperature Sensors
A 10K3A1 temperature sensor is a 10 kΩ NTC thermistor commonly used in HVAC/BMS applications. The designation generally refers to the 10K Type 3 / 3A1 thermistor curve.
Commercial Control Solutions
In today’s commercial real estate landscape, the integration of smart building technology is no longer a luxury—it is an operational necessity. At the heart of this technological evolution are Building Management Systems (BMS) and specialised HVAC Products. Together, these systems regulate indoor air quality, maintain thermal comfort, and optimise energy consumption across expansive facilities.
What is a 4-20 mA current loop?
The current loop is a common method of transmitting sensor information in many industrial process monitoring applications—typically in systems monitoring pressure, temperature, pH, flow, or other physical factors. These systems employ a two-wire current loop, in which a single twisted-pair cable supplies power to a transmitter and also carries the output signal.
Convert 4-20 mA to 0-10V
All iSMA Universal Inputs cannot read a 4-20mA signal directly, so to read a 4-20mA sensor, you will find in the box of every iSMA device (with Universal Inputs) a set of 200 Ohm resistors.
It is extremely simple to measure a 0-20 mA analogue signal from a sensor with a JACE that will measure only voltage inputs.

Niagara AX to N4 Migration
To use the Migration Tool provided by Tridium you will need a backup (.dist file) of a station that is running on AX 3.8, you cannot migrate only the bog file or a station running a version lower than 3.8.
