Characteristics
Installation
Positioning options
The modular unit is mounted on a DIN rail in the electrical
cabinet.
Installing the CTs (current transformers)
• The CT wire length can be extended by up to 1.5 m (for wire type H03VV-F or H05V-K).
• CTs do not have a connection polarity.
• It is important to check that the CT assigned to phase 1 (see connection diagrams) actually
measures phase 1 (the same must be done for phases 2 and 3).
• It is possible to pass several conductors from the same phase through a single CT (maximum
interior Ø 10 mm).
Starting up
When the TYWATT TRI is switched on, it determines the type of meter wired
to its terminals. This takes around 10 seconds:
- The red LED is on steady.
- The consumption total begins (in Wh up to 1 kWh (fig.1), then in kWh
(fig.2)), with no indication of the price period.
After 10 seconds:
- The red LED is on and steady if TYWATT TRI is operating with an
electronic meter (see § 6.5) or flashes if TYWATT TRI is operating with an
electromechanical meter,
- The current price period indicator is displayed (fig. 3).
Note: Switch on the heating. TWATT TRI’s operation can be confirmed immediately when the counting
begins (fig.1 or fig.2).

TYWATT TRI measures the number of kilowatt-hours consumed by part of a three-phase 230 V
powered electric system (heating, DHW, etc.). It can be used with electromechanical meters as well as
with three-phase electronic meters.
TYWATT TRI performs 2 types of totals:
C1 (cumulated total since first startup, non erasable)
C2 (cumulated total since last reset, erasable)
The current is measured by external measuring devices (current transformers, CT).
