Prerequisites for Balancing with TA-SCOPE
TA-SCOPE is one of the components in the powerful IMI TA methodology for balancing of hydronic systems.
The ultimate goal of every heating and cooling installation is to provide the desired indoor climate at the lowest
possible energy cost. This requires a fully controllable hydronic system. Achieving full hydronic control depends on
meeting three key conditions:
• Design flow must be available at all terminals.
• Differential pressure (∆p) across control valves must not vary too much.
• Flows must be compatible at system interfaces.
The best way to attain these conditions is to perform a balancing procedure using TA-SCOPE. Balancing ensures
that the plant actually performs as specified by the designer and operates the way the designer intended.
Switch on/off the units
The Handheld and Dp Sensor units are switched on and off individually.
The Handheld Information bar displays details on intensity of wireless signal and battery status for the connected
units.
Handheld
Press
on the keypad during 1 second to switch on/off.
Dp Sensor
Press
during 1 second to switch on/off.
Sleep Mode
Once the screen has dimmed and been set to sleep mode the Handheld unit is still active, touch any key to return
directly to the last screen used.
If a unit is switched off whilst in sleep mode and then started again the start position is the main menu and
previous actions are interrupted.
If a Dp Sensor is actively performing a logging function, it will automatically go into sleep mode after 15 minutes.
The logging process will then continue whilst in sleep mode.
If a Dp Sensor is not actively performing a logging function, the unit will automatically switch off if it does not
detect its paired handheld within 30 minutes.
Adjustments of display settings and sleep mode are performed in the Settings menu, see page 37.
Wireless Communication
On delivery TA-SCOPE is prepared for wireless communication.
No adjustments of settings or other actions are required.
If required the Handheld and Dp Sensor units can be connected via cable.
Wireless communication uses radio frequency and is therefore not
allowed in areas where other vital electronic devices can be disturbed,
i.e., near medical equipment and implanted cardiac pacemakers, in health
care facilities, aircrafts, blasting areas, areas with potentially explosive
atmospheres and other areas posted “turn off two-way radio”.
Cut the wireless connection from the Settings menu.
is displayed on the
antenna icon in the Information bar and the antenna led of the Dp Sensor
stops flashing.
When reactivating the wireless function the units should initially be
connected with the cable to establish radio communication. If wireless
communication stops due to the units being out of radio range, they will
automatically reconnect when back within radio range as long as the
Wireless Signal option is set to On.
