Inputs/outputs

4.1 Power supply![TECE SH-CD6-230 Regelverteiler and Control Distributor

• Power supply](https://manuals.plus/wp-content/uploads/2024/06/TECE-SH- CD6-230-Regelverteiler-and-Control-Distributor-Power-supply.jpg) 4.2 Heating/cooling (H &C) Input
  Purpose: This input allows switching the regulation mode for the system: Heating or cooling.
  Source of the signal:

  • A mechanical switch
  • A Heat Pump
  • A SH-SM paired on the SH-CU central unit as an ON/OFF device.

This solution allows getting a remote control of the H&C mode from the application. Format des Signals: Der Eingang kann potenzialfrei oder spannungsführend 230 V sein.

Only one device in the system should be able to select the H&C mode. Other possible H&C switch signal source (See 3.3)

• Central unit (set manual H&C mode in the installer menu of the central) DIP4/DIP5 = OFF/OFF.

• SH-HCM which embeds a H&C input DIP4/DIP5 = ON/OFF.

• Digital thermostat configured as a Master H&C thermostat in manual or automatic mode (only one thermostat per installation) DIP4/DIP5 = OFF/ON.
  If you have multiple connecting boxes SH-CD in the system, the H&C mode should be controlled by only one controller:

• Without central, the system considers the Connecting box set as Main SH-CD (please refer to 5.1.2) DIP4/DIP5 = ON/ON.

• With central:

• If the Connecting box controls the H&C mode, DIP4/DIP5 = ON/ON.

• If the Central unit controls the H&C mode, DIP4/DIP5 = OFF/OFF.

4.3 Pump Output
There are 2 outputs:

• Live contact output (230 Vac)

• Free contact output
  These outputs can be used to trigger:

• A zone valve

• A pump

• A boiler or heat pump
  The 2 outputs are triggered when there are a heating or cooling demand:

• In the controller if DIP switch 1 = OFF = local

• In the system if DIP switch 1 = ON = global See 3.3
  The delay between the heating or cooling demand and the pump activation is configurable:

• Pump starts 2 minutes after heating or cooling demand if DIP switch 3 = OFF

• Pump starts 5 minutes after heating or cooling demand if DIP switch 3 = ON See 3.3
  The purpose is to consider the latency of the actuator.

4.4 Contact for temperature limitation
This is a security input (Free contact).

The security input should be used on a controller with a pump.
When the contact is opened:

• The local pump output is stopped (even if DIP1=ON, i.e. global pump on the controller).
• The actuators are closed.
• The Pump/Drier LED is red blinking.
• The Heat and Cool LED is red blinking (in heating) or blue blinking (in cooling).
• If the controller is a sub controller, the heating or cooling demand is not sent to the main controller.

You can use a contact thermostat for thermal security. You can install 2 contact thermostats in serial to protect against both overheating and overcooling (The security input is valid in both heating and cooling mode).
The product is delivered with a strap on the connector.
Please note that the pump of the SH-HCM is triggered when at least one pump of the multiple SH-CD installed in the system is triggered.
4.5 Humidity detection input
The product has a humidity detection input.
2 possible types of signal according to DIP8 (See 3.3):

• A humidity contact sensor.
• Water temperature sensor (CTN 10 kΩ): Require SH-DTH thermostat.

4.5.1 Humidity contact sensor (dew-point control)
DIP8 = OFF
Format of the signal: The input is a free contact.

In cooling mode, when humidity is detected, the controller:

• Stops the pump signal.
• Closes all actuators.
• Sends the humidity alarm to all other SH-CD in the system.
• Requests the SH-HCM to enable the dehumidifier.

If the controller is a sub controller, the cooling demand is not sent to the main controller.
4.5.2 Water temperature sensor
DIP8 = ON
There are 2 usages of the water temperature measurement.
Humidity detection
In cooling mode, for each zone, the controller computes the dew point based on the ambient temperature and relative humidity sent by each thermostat (Thermostat with relative humidity sensor is required).
When the water temperature reaches the dew point in one zone, the controller:

the actuator of the zone opened for one hour then close the actuator and stop the cooling demand in the zone if the humidity alarm is still triggered.

• Enable remote dehumidifier of the zone.

• Requests the heat&cool module SH-HCM to enable the global dehumidifier for at least 15 min and up the disappea- rance of the alarm if no remote dehumidifier is available in the zone.
  If the controller is a sub controller, the cooling demand of the zone is not sent to the main controller.
  Heating&Cooling mode detection
  When DIP4 = ON and DIP5 = ON (H&C switch control = SH-CD) and DIP8 = ON the water temperature is used to automatically detect the H&C mode.

• If water temperature > 24°C, the system is in heating mode.

• If water temperature < 20°C, the system is in cooling mode.
  This feature is useful when the Heat Pump switches automatically in heating or cooling mode and has no output to inform the system.

• If the SH-HCM measures a water temperature:

• The temperature is sent to the SH-CD which can be used if there is no water temperature sensor.

• If H&C input = cool mode: The system switches in cooling mode regardless the water temperature.

4.6 NC/NO actuators
Connect one NC or NO actuator per connector.

• 230 V actuators for SH-CD-230
• 24 V actuators for SH-CD-24

The type of actuators is defined by DIP2.
It is necessary to use the same type for all actuators.
When there is a heating or cooling demand in one zone, the actuator is triggered immediately.
When the heating or cooling demand is stopped, the actuator is closed immediately except if this is the last actuator opened in the controller. In that case, the delay before starting to close the actuator is dependent of DIP3 (See 3.3):

• If DIP3 = OFF, the system waits 5 min before closing the last actuator
• If DIP3 = ON, the system waits 20 min before closing the last actuator

Justification: Many heat pumps have a built-in turn-off delay (to avoid successive switch OFF/ON). In this case, the heat pump continues to run for x minutes beyond the actual switch-off time. It is important to keep at least one circuit open unless there is a buffer tank, hydraulic switch or bypass in the installation.
4.7 External antenna
The controller embeds an internal antenna. If require, an external antenna can be connected to improve the RF communication. It could be useful if the controller is installed inside a metallic box. In that case, you need to install the external antenna outside the metallic box.
Please respect the mounting to optimize sensitivity and avoid any dysfunction.
Antenna must be installed:

• outside the metallic box
• in vertical position
• and at least at 50 cm of metallic parts.

If you have several antenna (several controllers), they must be placed at minimum 80 cm of each other.

5.1.2. Multiple controller’s installation
If there are multiple interconnected controllers in the installation, there are 1 main-controller (Main SH-CD) and up to 3 sub-controllers (Sub SH-CD).
The main controller centralizes the information for the sub-controllers. If a heat-cool module SH-HCM is used, it should be paired to the main-controller.

• The main controller propagates the Heat and Cool mode to the sub-controllers. This information could come from the SH-HCM or from a Master Digital thermostat according to the DIP4 and DIP5 (See 3.3)
• The main controller could handle the pump signal of the whole installation according to DIP1 (See 3.3)

Exit of the controller pairing menu: Long press on .

5.3 Control a dehumidifier per room.
There are 2 ways to detect humidity:

• At controller level using the humidity detection input (See 4.5).
• At the room level if the thermostat embeds a relative humidity sensor. When humidity is detected, there are 2 ways to trigger dehumidifier:
• A global dehumidifier is triggered by the SH-HCM if the feature is activated on SH-HCM.
• A dehumidifier is triggered on the room level where the humidity is detected.

For that case, you need to pair a SH-SM receiver on each zone of the controller to trigger a dehumidifier.

By pressing  for 5 seconds, the controller goes in RF pairing menu.
By using    select zone 4 (LED blinks red), press to enter in dehumidifier Pairing mode.
Choose the zones with    .
Zones are defined by paired thermostat channels.
