8.2.4. Main Select Screen
The seventh screen (or accessed by pressing F2
on the HHT) will allow the user to select what
sub-system should be accessed. (Defaults to 1.)
8.2.5. Valve Configuration Screens
The Option 1 screen will enable the user to view
valve configurations and to make temporary
changes to the settings. However, once the HHT
is removed, the settings will go back to the val-
ues programmed at the E2 if online. (Defaults
are Flow Control’s ESR 12 and ESR 20 valves.)
Use the up and down arrows to select the desired
valve (1-8). Use the right arrow to select the de-
sired fields.
• Valve: 1 - can be set to Other or ECT Flow
• Max Steps - can be set from 1 - 10000 . De-
fault is 800 .
• Rate - can be set from 20 - 500 . Default is 50 .
• OvrCls - can be set from 0 - 20 . Default is 5 .
• Fail % - can be set from 0 - 100 . Default is
100 .
For Valve, choose the type of valve being used.
Set to
ECT Flow for ECT valve types or Other
for any other type of valve.
Max Steps is the total number of steps the valve
travels between fully closed (0%) and fully open
(100%).
Rate corresponds to the step rate of the valve (in
steps per second). The default, 50 steps per sec-
ond, is the correct step rate for the ESR 12 and
ESR 20 valves.
OvrCls is the Over Close percentage that will be
used when setting a valve to 0% for defrost.
Fail % is the failsafe output percentage to use if
communications are lost with the E2.
8.2.6. Network Screen
The Option 2 screen will show the network set-
tings for the MultiFlex ESR controller. There are
no editable fields on this screen. This display is a
reflection of the dip switch settings:
