remote input type
(0-10V or 4-20mA; default 0-10v)When operating in
ANALOG Control Source, the LTC I/O Board accepts
a Remote Hot Water Setpoint offset in the form of either
a 0-10Vdc or 4-20mA input to the LTC I/O Board input
(TB9-3/4). This setpoint configures the LTC I/O Board
input to accept the input signal type applied. Only ap-
pears when the Hot Water Control is set enabled and the
CONTROL SOURCE setpoint (Operations Screen) is
set to ANALOG.
Control Valve output settings - type
(0-10v or 4-20mA; default 0-10v) Sets the output signal
to the Control Valve to be in the form of either 0-10Vdc
or 4-20mA. Only appears when Hot Water Control is
enabled or Head Pressure Control is enabled.
Control Valve output settings - pid output
(Direct or Reverse) Allows the output signal to the
Control Valve to be set to DIRECT or REVERSE act-
ing. When set to DIRECT, the voltage or current signal
to the Control Valve is at minimum for a 0% command
and at maximum for a 100% command. When set to
REVERSE, the voltage or current signal to the Control
Valve is at maximum for a 0% command and at mini-
mum for a 100% command. Only appears when Hot
Water Control is enabled or Head Pressure Control is
enabled.
Control Valve output settings - set
(0.0% to 100%; default 0.0%) Allows the Control Valve
to be manually set to a pre-determined position between
0.0% and 100%. Only appears when Hot Water Control
is enabled or Head Pressure Control is enabled.
Control Valve output settings - auto
Places the Control Valve in automatic control. Only
appears when Hot Water Control is enabled or Head
Pressure Control is enabled.
