PART 1

INTRODUCTION

1.1 Description

The iTH Series instruments monitor and control both temperature and relative humidity.

• Used with an iTH probe the controller comes with dual displays. The top displays
relative humidity and the bottom displays temperature. Relative Humidity can be
toggled with Temperature readings (by pressing the bbutton) or Dewpoint readings
(by pressing the cbutton). Dewpoint is the temperature at which water vapor from
the air begins to form droplets and condenses on surfaces that are colder than the
dewpoint of air.

• The temperature and humidity control can be achieved by using on/off or PID
heat/cool control strategy. Control can be optimized with an auto tune feature. The
instrument offers a ramp to setpoint with timed soak period before switching off the
output.

The instruments are simple to configure and use, while providing tremendous versatility
and a wealth of powerful features. The iTH Series instruments are available either as
monitors or controllers. The monitors are extremely accurate programmable digital panel
meters displaying humidity, temperature, or dew point. The controllers also provide dual
loop control for both humidity and temperature and are easily programmed for any
control or alarming requirement from simple on-off to full autotune PID control.

The iTH family of meters and controllers are available in four true DIN Sizes with NEMA 4,
IP65 splash resistant bezels: the ultra compact 1/32 DIN (the world's smallest dual loop
Humidity + Temperature controller); the popular midsize 1/16 DIN square bezel with dual
display; the 1/8 DIN vertical, and the 1/8 DIN horizontal with the big bright 21mm digits.

The iTH series LED displays can be programmed to change color between Green,
Amber, and Red at any set point or alarm point.

The iTH controller models offer a choice of two control or alarm outputs in almost any
combination: solid state relays (SSR); Form "C" SPDT (Single Pole Double Throw)
relays; pulsed 10 Vdc output for use with an external SSR; or Analog Output selectable
for control or retransmission of the process value. Universal power supply accepts 90 to
240 Vac. Low voltage power option accepts 24 Vac or 12 to 36 Vdc.

The Networking and Communications options include direct Ethernet LAN connectivity
with an Embedded Web Server, and serial communications. The -C24 serial
communications option includes both RS-232 and RS-485. Protocols include both
MODBUS and a straightforward ASCII protocol. The -C4EI option includes both Ethernet
and RS-485 ASCII/MODBUS on one device.

The iTH Series meters and controllers are designed for easy integration with popular
industrial automation, data acquisition and control programs as well as Microsoft Visual
Basic and Excel. provides free configuration and data acquisition software and demos
which makes it fast and easy to get up and running with many applications.

2.3 Electrical Installation

2.3.1 Power Connections

Caution: Do not connect power to your device until you have completed all

input and output connections. Failure to do so may result in injury!

Connect the main power connections as shown in Figure 2.4.

Figure 2.4 Main Power Connections

Table 2.3 Fuse Requirement (see specifications)

FUSE Connector Output Type For 115Vac For 230Vac DC
FUSE 1 Power N/A 100 mA(T) 100 mA(T) 100 mA(T)
FUSE 2 Power N/A N/A N/A 400 mA(T)

For the low voltage power option, in order to maintain the same degree of
protection as the standard high voltage input power units (90 - 240 Vac),
always use a Safety Agency Approved DC or AC source with the same
Overvoltage Category and pollution degree as the standard AC unit (90 ­240 Vac).

The Safety European Standard EN61010-1 for measurement, control,
and laboratory equipment requires that fuses must be specified based on
IEC127. This standard specifies for a Time-lag fuse, the letter code “T”.
The above recommended fuses are of the type IEC127-2-sheet III. Be
aware that there are significant differences between the requirements
listed in the UL 248-14/CSA 248.14 and the IEC 127 fuse standards. As a
result, no single fuse can carry all approval listings. A 1.0 Amp IEC fuse
is approximately equivalent to a 1.4 Amp UL/CSA fuse. It is advised to
consult the manufacturer’s data sheets for a cross-reference.

Alarm 2 Menu.

The above example (also the factory default) is for 0-10 V of the entire
range of the Humidity Input and Analog Output. For 0-20 mA output you
need to set “Analog Type” to Current and OUT 2 to 20.00.

23

Accuracy of Analog Output board is +/-1% of FS (Full Scale) when following
conditions are satisfied:

1. The input is not scaled below 1% of Input FS (10 mV @ 1 V or 0.2 mA @
20 mA input ranges).

2. Analog Output is not scaled below 3% of Output FS (300 mV @ 10 V or

0.6 mA @ 20 mA output ranges).

Otherwise certain corrections need to be applied.

For example:

For entire range of Humidity Input, the Analog Output on 10 V FS scaled for
300 mV output range:

Rd1 = 0000, Out1 = 00.00
RD2 = 100.0, Out2 = 00.30

The measured output will be as follows:

Rd1 = 0000, Out1 = -0.07 V
Rd2 = 100.0, Out2 = 0.23 V

This means that for 300 mV output range we have -70 mV offset at zero and at
full scale. In order to compensate this 70 mV offset the correct scaling will be
as follows:

Rd1 = 0000, Out1 = 00.07
Rd2 = 100.0, Out2 = 00.37

The above corrections need to be applied only for Input scaled below 1% of FS
and Output scaled below 3% of FS or if you need the Analog Output

accuracy to be better than 1% of FS.

Setpoint Deviation Submenu, if “enabled”, allows changes to Setpoint 1 to be
made automatically to Setpoint 2. This mode is very helpful if the Process Value
changes often. In Setpoint Deviation Mode, set SP2 a certain number of degrees
or counts away from SP1 - this relation remains fixed when SP1 is changed. For
instance: Setting SP1=200 and SP2=20 and enabling

SP.DV

means that the
absolute value of SP2=220. Moving SP1 to 300, the absolute value of SP2
becomes 320.

The ON/OFF control is a coarse way of controlling the process. The “Dead
Band” improves the cycling associated with the On/Off control. The PID control is
best for processes where the Setpoint is continuously changing and/or a tight
control of the process variable is required. PID control requires tuning and
adjustment of the "Proportional", "Integral or Reset" and "Derivative or Rate"
terms by a trial-and-error method. The instrument provides an "Auto Tuning"
feature making the tuning process automatic, possibly optimum.

. This way the microcontroller knows
which one of the outputs to Autotune for Temperature or Humidity. Also,
the controller is ready to calculate P, PI or PID parameters. The
instrument performs this by activating the output and observing the delay
and rate at which the Process Value changes. The setpoints must be at
least 18°F (10°C) or 10%RH above the (PV) Process Value in order to
perform Auto Tune, otherwise an error message will be displayed.

To start Auto Tune PlD select PID, enable Auto PID and enable Start PID.
Sometimes Auto PID parameter needs fine tuning i.e. for each 5°F over
shoot increase the Proportional Band (PB) by 15% and for each ±1°F
fluctuation at the Setpoint (SP) increase reset by 20%.

Once started, display shows A.TUN with letters blinking in the rotating
pattern. When auto tune stops, display will show process value. Do not
perform any operations or settings before first stopping Auto Tune. Any
alarms or other output is disabled during Auto Tune.

If “AUTO PID” was “DISABLED”, the display will show the following
three submenus. This allows the user to manually enter values for
Proportional, Reset and Rate terms corresponding to P, I, and D. It also

Damping Factor is a measure of speed, overshoot, and undershoot in which the
process variable responds to the output changes of the instrument, which were
used during the Auto Tune. This value is typically set to the ratio of Rate to
Reset. This Default value is (0003). For fast response time, this value should be
decreased while for slow response time it should be increased.

Ramp & Soak provides users with the flexibility to slowly bring the Process
Variable (PV) to the desired setpoint. Ramp & Soak values are specified in
HH.MM format. The Ramp value indicates the time specified to bring the
process variable to Setpoint 1 (SP1). Once the set point is reached, the PID
takes over and the Process Variable will be controlled at the desired set point
indefinitely. If Soak is enabled, PID will control the Process Variable at the
specified Setpoint for the duration of Soak time and then will turn off Output 1.
To start a new Ramp/Soak cycle, reset the instrument by pressing aand then

c

button.

An active Ramp/Soak will change SP1 one degree above the PV and will cause
the most significant digit to blink. The SP1 will be incremented by one degree
until it reaches the original SP1. The minimum Ramp time must be at least twice
the time that it will take the PV to reach the Setpoint Value (SV) with OUT 1 fully
