(ESN) that are unique for each series TF1100heat meter.

M62

RS232C communication setup

Commonly, user should select

“9600, None”

9600 is baud rate, check bit

is “None”.

M63

Analog input temperature sensor range value for heat flow

application, wiring terminals is Tin+, Tin-. Press ENTER and

use key

∧

∨

to input value corresponding 4mA and

20mA

M64

Analog input temperature sensor range value for heat flow

application, wiring terminals is Tout+, Tout-. Press ENTER

and use key

∧

∨

to input value corresponding 4mA and

20mA

M65

Setup the frequency range for the frequency output. The

biggest range is 0Hz-9999Hz. Default value is 1-1001 Hz.

M66

Setup the Low Frequency Output

Corresponding Value of Flow Rate.

This value correspond to the lowest

Frequency value entered in M65.

M67

Setup the High Frequency Output

Corresponding Value of Flow Rate.

This value correspond to the highest

Frequency value entered in M65.

Please see the *Note for wiring diagram.

M70

LCD Backlit option. User can select “Always On”, Always

Off” or “Lighting for” items, if select “Lighting for”, please

entered a second value, it indicates how many seconds the

backlight will be on.

M71

LCD contrast control. The LCD will become darker when a

small value is entered.

M72

Working timer. It can be cleared by pressing ENTER key, and

then select YES.

M73

Alarm #1 Low Value

Enter Lowest Flow Rate value that will trigger the Relay
