4.3 Additional functions

The controller, as well as the control algorithms for the various types of applications (air-conditioners, boilers, heat pumps, condensing units,...), features a series of additional functions, as described below.

Change night/day mode manually (NIGHT)

This activates the opposite function to the current (night if day or day if night), for the set time. Pressing the NIGHT button once accesses the timer menu and displays the duration. To change the duration of the temporary mode use the UP/DOWN buttons. To change the value of the timer permanently, access the Prg menu and set parameter SLP. To set the current timer to zero and return the instrument to the original mode, press the NIGHT button, the remaining time is displayed, then press DOWN until reaching the value 0. The instrument, after having brie y displayed the message OFF SLP, automatically returns to the main menu. Once having set the timer, pressing the NIGHT button displays the time remaining on the timer. This value can be changed at any time. To exit the menu press the NIGHT button again.

Example of operation with time bands:

RTC:  tted and con gured, the time is 15:55, the symbol is on dAy: 8:00 nIt: 16:00 At 16:00 the controller will switch to Night mode with a lower (in heating) or higher (in cooling) temperature setting. Assuming the user wants to extend Day mode for a further 3 hours, having to work late in the o ce.

The following operations are required:

press the NIGHT button;• set the timer to 3h and 00’ using the DOWN button;• press the NIGHT button to con rm the setting.•

The clima returns to Day mode with the corresponding set point. It will automatically return to Night mode according to the time bands when the timer reaches zero.

4.2 Main parameters to be set

AThe parameters for each operating mode also feature a default value, and these values can be restored by running the “Factory set” operation. The default values are the same for all eight modes. See the table of parameters for details of the default values and settings.

Initially at least the following parameters need to be checked/set:

SET POINT:

• depending on the operating mode, di erent set points

are sued. To set these, access (SET button – 5 seconds) the mode for setting the parameters and set the corresponding values. For the current mode only, the value can be accessed directly using UP, DOWN or set, UP, DOWN (for the SMALL  eld). The following set points need to be de ned:

set point for temperature control•

Daytime (def. 20.0 °C) and night set point (def. 18.0 °C) in heating – Daytime (def. 24.0 °C) and night set point (def. 26.0 °C) in cooling –

set point for humidity control•

Humidi cation set point (def. 30.0 % RH) – Dehumidi cation set point (def. 70.0 % RH) –

Clock, • TIME BANDS Prg/ (clock): Press the corresponding button to display and if necessary set the default duration of the change mode timer, display or set the RTC clock and set the Day and Night time bands.

Sensor calibration

To make up for any errors due to the length of the cables or the sensors connected, the controller features two parameters for calibrating the values read by the sensors.

The following parameters are involved:

AUTO humidity control

In addition to the modes featured by the control algorithms, the humidity can be controlled automatically, based on the reading of the outside temperature sensor. The aim of this type of control is to simplify the setting of the clima, changing the humidity control according to the outside environmental conditions and therefore minimise the discomfort of the user when moving into/out of the air-conditioned environment. This operating mode is selected by setting parameter AUT. According to the level set using the up/down buttons, with a value from

1 to 7, a di erent humidity set point trend is de ned. To disable this operating mode, in the parameters menu set the value of Aut = 0. AUTO mode for the humidi cation control is only possible if the outside temperature sensor is installed.

Average of the temperature readings between the built-in sensor and the remote sensor

This temperature control mode is based not only on the reading of the built-in sensor (TI), but also the outside temperature sensor (TE). It is in essence a weighted average of the two temperature measurements:

Tm = (TI * (100-nEd) + TE *nEd)/100 Def.=0 (built-in sensor only)

This operating mode is only possible if is the remote sensor is installed, otherwise the instrument shows a remote sensor error and only uses the built-in sensor for control. The average value is both used for control and shown on the display.

Temperature set point compensation based on the outside temperature

For control that considers the outside temperature, the outside temperature sensor can be connected to compensate the temperature set point. Such compensation, once activated, is the same for all control modes, day, night, cooling and heating. Parameters Cts and Ctt de ne the di erence between the set point and the outside temperature above which compensation is activated. Parameter CSt de nes the compensation factor and CdF the maximum set point compensation allowed.

Cooling control:

SP comp. = setpoint + (Text – set point – CtS) * CSt

Heating control: SP comp. = setpoint – (set point – Text – Ctt) * CSt

The maximum correction value is limited by parameter CdF, that is, if the compensation calculated is higher (cooling) or lower (heating) than CdF, the controller uses ± CdF as the maximum compensation value. The weight of the correction is de ned by CSt, set in tenths of °C from

-1 to +1.

Control the outputs via RS485 serial connection

The status of the analogue output and the relays on the instrument can be controlled via a serial connection to a supervisor.

The variables are read only if LIn=no, or read/write if LIn=yES The variables are described in the table of supervisor variables and must be used according to the current mode (T, T2, T2A,...), the status on the LCD automatically shows the outputs.

Important: This function, if enabled, completely replaces the

control performed by the instrument. In this operating mode, together with the outputs, the symbols displaying the operating status of the instrument are also activated according to the current mode.

Note: If the instrument is not queried for more than two minutes,

“override” mode is disabled:

all the outputs are disabled;• the no link error (ELn) is signalled on the display.•

Remote temperature/humidity sensor

For the models without the humidity sensor already installed, a remote sensor for ducts (temperature + humidity) can be connected, up to a maximum distance of 3 m. The sensor is purchased separately, code ADCF006500. This code includes the wired cable in the maximum available length (3 m). The remote temperature/humidity sensor can be installed on all ADCA*** codes.

Note: The remote temperature/humidity sensor cannot be

connected to controller codes ADCF*** and ADCD*** that already have a built-in humidity sensor, as this would cause the temperature and humidity measurements to freeze. To retro t a clima model ADCF*** or ADCD*** already installed with a remote sensor, open the controller and remove the plug-in card with the temperature/humidity sensor from the PCB, as shown in the  gure.

range def. UOM

This chapter describes the temperature and humidity control modes available. The control modes for the di erent models of clima are based on a set of parameters, divided into two levels:

Level 1, basic:

• main settings, always required;

Level 2, advanced:• used to customise the features of the controller.

Important note: Some parameters included in the advanced

level, are forced to take on default values in the basic level or are linked to other parameters in the basic level. This rule especially applies to the control di erentials. In each operating mode, the links between the various basic and advanced levels are speci ed.

Note:

Parameters with forced values are NOT visible from the supervisor:

if level 1 is active, the level 2 parameters are not used but rather • replaced by the default values or by the link value with the level 1 parameters; the supervisor can read and set the level 2 parameters that are however not e ectively used for the control functions. the level 2 parameters are e ectively used when level 2 is activated.•

5.1 (T) temperature control with single output

This is used in simple applications to send a start signal to an airconditioner or heat pump/boiler via the relay. The analogue output can be used alternately or together with the relay output to:

control a modulating hot or cold water valve;• as an additional proportional control step to the relay.•

Dipswitch con guration:

dip1: OFF dip2: ON dip3: OFF

This control mode is available in both cooling and heating mode, the selection is made using dipswitch 4, or from the supervisor serial connection or digital input. Depending on the value of LE (level), either only the basic parameters (LE=1) or all (LE=2) can be set.

The typical application is the control of a classic system with airconditioner + boiler and humidity control using a CAREL proportional humidi er, for example the compactSteam series. Dehumidi cation is performed using the air-conditioner, making sure that the temperature conditions are within the comfort limits.

There are two humidity set points, one for humidi cation and the other for dehumidi cation; the changeover points for automatic humidi cation/ dehumidi cation operation are also de ned.

There is just one temperature set point for both cooling and heating, the changeover (cooling/heating) occurs based on the activation points of the two outputs.

Dehumidi cation can only be activated if the humidity exceeds the dehumidi cation set point plus the di erential dFd, and furthermore: Temp > Set – dS1 – dF2

It is deactivated if the humidity is below the dehumidi cation set point and in furthermore: Temp < Set – dS1 – dF2 – 0.5 °C

For the control of a classic reverse-cycle air-conditioning system, with automatic cooling/heating changeover and proportional humidity control using the CAREL compactSteam humidi er. Automatic operating mode is signalled on the display by the AUTO symbol, next to the set point.

There are two set points, one for cooling and the other for heating, and both can be set. The mode switches between cooling and heating automatically according to the room temperature measured. The two set points are set by pressing the SET button or the UP or DOWN button,  rst the cooling set point is displayed and then the heating set point, the controller automatically checks that there is a di erence of at least 1°C between the two set points.

Relay 1 controls the heating/cooling signal. The analogue output controls humidi cation. Relay output 2 manages the changeover in mode.

5.8 (T+H radiant ON/OFF) ON/OFF mode for radiant  oor systems

ON/OFF control mode in radiant systems is available for all models of clima (ADCA*, ADCD*, ADCF*), both with temperature control only and temperature plus humidity (modes T or T + H), and is likewise available for the speci c model for radiant systems, ADCF000610. Temperature control uses one relay only:

R1 for models ADCA000210, ADCA000410 and all models ADCF*;

•

R2 for models ADCA000100, ADCA000110 and all models ADCD*;•

The second relay (R2), if available, is associated with humidity control, as is the analogue output.

Dipswitch con guration:

dip1: OFF dip2: OFF dip3: OFF

The remote sensor is used to control the water outlet temperature, and this must be installed, otherwise an error is signalled. For control two parameters are used that de ne two thresholds for the water temperature:

maximum temperature, in heating mode (EHi);

•

minimum temperature, in cooling mode (ELo).•

To protect the system against critical operating conditions, if such limits are exceeded, an alarm is signalled, EHi (high temperature) or ELo (low temperature) and the actuator is deactivated (relay). For the control mode, see the modes T and T+H, the speci c additional parameters are as follows:

5.9 Proportional control mode for radiant  oor systems (code ADCF000610)

The control functions use:

built-in temperature sensor for the room temperature measurement;

•

humidity sensor to avoid condensation in cooling mode;• remote temperature sensor for measuring the heating/cooling water • temperature, which must be installed, otherwise an error is signalled; ON/OFF output (R1) as the general signal for controlling the zone • valve/valves; proportional 0 to 10 V output for the control of the mixing valve;• ON/OFF output (R2) for humidity control.•

The dipswitch settings for this speci c model of clima allow operation to be selected between ON/OFF and proportional, with di erent parameter con gurations saved by setting the individual DIP con gurations, as shown in the table; these can then be recalled by the user based on the selected set of parameters.

The table summarises the con gurations that can be selected:

Control calculation:

Based on the proportional error (Temperature measured – set 1. point) and the integral error, the clima automatically calculates the water outlet set point. The calculation uses the parameters corresponding to the active operating mode (cooling or heating) active: tHH, tHL, tAH, tAL, where dIF = tAH–tAL. The integral error is only calculated within the control interval, tAH–tAL according to parameter tIn (integration time). The  gure shows an example where when the room temperature = room set point and the total error is null, the water outlet set point is 34 °C (for radiant  oors). The ON/OFF output (R1) is activated when the room temperature

is less than the maximum limit tAH. This output sends the signal to activate the system controller. The water outlet temperature is controlled based on the set 3. point calculated (in point 1) and with a  xed di erential of 4 °C. The control functions use the remote sensor, installed on the outlet manifold:

If the water temperature is greater than or equal to the set point

•

calculated, the valve is closed. If the water temperature is less than (set point – 4 °) the valve is • completely open. In intermediate situations the valve is open proportionally to the • deviation from the set point calculated.

To avoid excessive  oor temperatures, the maximum water 4.

temperature is compensated, which may be lower than the maximum value set for tHH. This occurs when the system responds, during heating, with excessively fast variations of the room temperature. In the  gure this operation is indicated by the dashed line, the line at the bottom, for example, de nes a water set point of around 29 °C rather than 34 °C for the same room temperature. The calculation of the maximum value for tHH is based on parameter tr, which de nes an observation time in minutes on the value of the integral error:

If within the time tr control is active (valve open) and there is an • increase in temperature greater than 0.5 °C => tHH is decreased by 1 °C. If, always in the observation period (tr), the variation was less than •

0.5 °C but the integral error is positive (>20% of dIF) => tHH is again decreased by 1 °C. If, on the other hand, the variation is less than 0.5 °C but the integral • error is negative (>20% of dIF) => tHH is increased by 1 °C. Recommended value of tr = 30 min., yet this depends on the inertia • of the system and the integral error set (tIn).

Note: the value of tHH is not modi ed as a parameter, rather an

o set is added or subtracted. The purpose of the maximum set point compensation for the water temperature is to make the system work with the lowest possible  oor temperature. In operating conditions outside of the room temperature limits, tAH or tAL, the initial conditions are restored for tHH.

Note: When the temperature is read on the SMALL  eld,

the H2O symbol is shown to indicate that this is the system water temperature.

Note: Parameter LE=1 or 2 has no in uence on the settings of the

parameters.

The same rules apply as for heating control, with the following di erences:

The values of the parameters are di erent for cooling, in particular tHH • and tHL; The control of the modulating valve is reversed with reference to the • water temperature set point: if the temperature is greater than the set point, the valve is open. The compensation of the temperature limit is activated using tHL • rather than tHH, and the logic is reversed: tHL is increased rather than decreased. There is also another limit on the water temperature set point: based • on the estimated dewpoint, the set point is limited to values greater than Temp_dew + ddP (dewpoint di . parameter).

Note: the value of tHL is not modi ed as a parameter, rather an

o set is added or subtracted. The purpose of the minimum set point compensation for the water temperature is to make the system work with the lowest possible  oor temperature, so as to maximise cooling. In operating conditions outside of the temperature limits greater than tAH or less than tAL, the initial conditions are restored for tHL.

Humidity control for proportional radiant operation: Code ADCF000610 also uses the humidity sensor, for two functions:

In cooling mode, it is used for the estimate the dewpoint.

•

It can also be used for ambient humidity control, via relay 2, connecting • an external humidi er/dehumidi er.

Note: In the supervisor parameters, the set point for the automatic

modes (day and night) is saved to both values (cooling/heating); when setting, simply change the heating set point only, and the setting will be automatically copied to the corresponding cooling set point.

Note: All the analogue variables (set point, di erential, sensor

calibration ...) are expressed in tenths if read with the CAREL protocol, while they are expressed in hundredths if read with the Modbus® protocol (example: 24.3 °C: CAREL supervisor = 243, Modbus® supervisor = 2430)
