1.  INTRODUCTION

The IC-410ND is a programmable regulator that can be used in different types of buildings simply by changing its logic, called “configuration”. The logic configuration is a program that creates a relationship between the inputs and the parameters to activate the outputs. This program is memorized in a module identified by a configuration number. We kindly ask you to mention this number when discussing with your supplier.

For proper installation and full understanding of your IC-410ND, it is important for you to read the IC-410ND User’s Manual and this Control Logic Document. The User’s Manual informs you on safety issues, warranty, sensors, adjustments of parameters and many other characteristics of the IC-410ND. However, this document explains all particularities of this configuration logic.

Definition

Throughout this document, the following terminology is used.

-DRT ® Desired Room Temperature. This is the temperature goal for the room and also the reference temperature for all relative settings. Note that the DRT is affected by the growth curve function, see also Growth Curve Function paragraph in the IC-410ND manual.

-RSP ® Relative Set Point. Number of degrees relative to the DRT where a function begins.

-Min Speed ® This is the user adjustable minimum speed for the variable speed fans.

-Mod Band ® Modulation Band is the number of degrees that a variable fan takes to reach its full speed.

-Diff ® Differential is the number of degrees changed before stopping the output. For example, with a differential = 1°F, the IC-410ND turns on a fan at 70°F when the temperature increases, but it will shut off at 69°F when the room is cooling down. The differential is necessary to avoid oscillations.

Expressions in ITALICS are user’s parameters whereas expressions in COURIER are supervisor’s parameter. Supervisor’s parameters are read-only for the user.

Ventilation System Overview

The building is divided in four zones. Each zone is equipped with its own temperature probe. Zones A and B each contain four balloon stages, while zones C and D only have two. Each zone is equipped with drying and defrost capabilities.

important Notes :

Ø  The balloons controlling natural ventilation close the air inlet when inflating and open the air inlet when deflating.

Ø  Two consecutive stages of a given balloon may not inflate at the same time. A fixed delay of one minute is used to prevent two or more stages from activating at the same time.

Ø  The stages of a given balloon must have ascending RSPs, stage 1 being the lowest and stage 4 the highest RSP, otherwise, balloons may have erratic behavior.


2. LOGIC DESCRIPTION

This configuration uses the Fahrenheit temperature unit.

Parameter # 1:

CLOCK

Displays the time of day in 24-hour format.

F2: ADJUST MINUTES

Used to adjust the minutes of the CLOCK.

F3: ADJUST HOURS

Used to adjust the hours of the CLOCK.

Parameters # 2-5:

ZONE A (B, C, D) TEMPERATURE

These parameters display the temperature read by the probe of the respective zone. ZONE A (B, C, D) TEMPERATURE is used to control the balloon stages of the respective zone. These temperatures are displayed to the nearest 0.1°F from -6.0°F to 168.6°F.

F2: See Note 1.

F3: See Note 2.

Note 1:

PROBE LOCATION

This function is used to display the physical location of a given probe. The value should always show the letter P, followed by the number of the input in the first two digits of the LED display. The other digits will display temperature read by that probe.

Note 2:

HI/LO RECORD

In addition to the readout of the probe, the parameter can record the lowest and highest value reached. To access the Hi/Lo function, press F3. To clear the respective Hi/Lo values, after pressing F3, press and hold the + and - buttons until CLR appears on the LED display.

Parameter #6:

DESIRED ROOM TEMP (DRT) ZONE A

The DRT ZONE A establishes the temperature goal for zone A. This value is also used as the reference point for all relative set points (RSP) of zone A. This parameter is adjusted in 0.1°F increments from 32.0°F to 120.0°F.

F2: DESIRED ROOM TEMP (DRT) ZONE B

The DRT ZONE B establishes the temperature goal for zone B. This value is also used as the reference point for all relative set points (RSP) of zone B. This parameter is adjusted in 0.1°F increments from 32.0°F to 120.0°F.

Parameter #7:

DESIRED ROOM TEMP (DRT) ZONE C

The DRT ZONE C establishes the temperature goal for zone C. This value is also used as the reference point for all relative set points (RSP) of zone C. This parameter is adjusted in 0.1°F increments from 32.0°F to 120.0°F.

BALLOON A RSP STAGE 1

This parameter sets the temperature at which stage 1 of balloon zone A will inflate. Below this RSP, stage 1 of balloon zone A may deflate according to the minimum ventilation timer (see parameter 15). Otherwise, stage 1 will deflate when ZONE A TEMPERATURE reaches DRT ZONE A + BALLOON A RSP STAGE 1 + DIFFERENTIAL ZONE A. This parameter is adjusted in 0.1°F increments from -10.0°F to 30.0°F.

Parameter # 14:

DEFROST ON TIME

This parameter allows the user to set the amount of time during which a balloon stage will deflate when in its defrost cycle. When a given zone receives a demand for defrosting, the first inflating stage will deflate for DEFROST ON TIME. It will then return to inflating (if temperature still requires so) for DEFROST ON TIME + 1 minute. After that period, the next stage of the balloon will execute the same sequence and so on until all stages have performed the defrost cycle. When in a defrost cycle, the “Defrost” LED will light up to warn the user. This parameter is adjusted in 1 second increments from OFF, 1 to 900 seconds.

F2: DEFROST OFF TIME

This parameter allows the user to set the amount of time between two defrost cycles. When a balloon of a given zone has completed a defrost cycle, the next defrost cycle will occur only after the DEFROST OFF TIME has elapsed. This parameter is adjusted in 1 minute increments from 2 to 480 minutes.
