HOTEL SOLUTION™

Room operator unit HTC3.2/..

Room unit to operate individual room control systems in hotel rooms

•Displays room temperature setpoint and setpoint adjustment

•Individual setpoint adjustment with "plus" and "minus" membrane switches

•Individual manual fan-speed selection for fan control (up to 3 speeds) or

selection of "Auto" operating mode

•Measurement of room temperature with a built-in or externally connected

temperature sensor

Application

The HTC3.2 operator unit for control of indoor room conditions is used in conjunction

with the HRC3.1/HRC3.2 room controllers. The room operator unit detects the

temperature and transmits it to the HRC3.1/HCR3.2 room controllers for room

temperature control. The room operator unit displays the operating mode in the hotel

room and can be used to operate the fan coil unit, either manually or automatically via

the connected room controller.

The guest can use the room unit to do the following:

•Adjust the preset room temperature setpoint by ±2 K or by ±4 K in eight steps. The

step size of 0.5 or 1.0 K can be configured in the room controller. The eight

temperature-change increments are indicated by a horizontal scale across the center

of the LCD display panel.

•Enable fan speeds 1, 2 and 3 manually

•Change from manual to automatic mode ("Auto")

Switching to "Auto" causes the fan speed to be set automatically by the controller

(Speed 1, 2 or 3). The fan status is indicated by symbols across the bottom of the LCD

display panel.

The temperature setpoint valid for the room is displayed in digits on the LCD display

panel. Throughout the period for which the guest is checked in, the individual setpoint-

setting remains valid. It cannot be overwritten by the hotel service staff.

When the guest leaves the room (removing the access card from the card holder) the

system switches automatically to "Auto", and the "Precomfort" room operating mode

with the energy-saving function (widening of the deadband) comes into effect. When

the guest returns to the room, the "Auto" mode remains active and the "Comfort" room

operating mode, with the guest's personally selected setpoint adjustment, is restored.

In conjunction with the HOTEL SOLUTION system, the room temperature setpoints

preset for a given room are automatically re-instated when the guest checks out.

Engineering notes

Base frame The room unit is designed for flush wall mounting in conjunction with base-frames and

cover plates from various manufacturers:

•Bticino Living for HTC3.2/BB

•Bticino Light for HTC3.2/BW

•Vimar Idea for HTC3.2/VB

•Vimar Plana or Ikon for HTC3.2/VW

Up to 4 room units may be connected to one room controller.

STOP Important note The maximum permitted current associated with the supply voltage from the

HRC3.1/HRC3.2 room controller must not be exceeded.

(For further information, see data sheet CM2N6313 and CM2N6314.)

Addressing The room temperature control algorithm is not in the room unit itself, but in the

controller application. To enable the room controller to communicate with the room unit,

the latter must be assigned with an address.

The addresses of the room operator units are set by DIP switch on the back of the

room comfort operator unit.

First room operating unit ADR0=0, ADR1 = 0

Second room operating unit ADR0=1, ADR1 = 0

Third room operating unit ADR0=0, ADR1 = 1

Fourth room operating unit ADR0=1, ADR1 = 1

Configuration menu The room operator unit includes a configuration menu for setting certain parameters.

After a restart, the configuration menu can be displayed as follows:

1. Hold down

2. Press and hold

3. Release

4. Release

STOP Important note The configuration menu can only be displayed provided that no other buttons are

pressed when the room operator unit is restarted.

The configuration menu is identified as shown below.

Opening display

The buttons are used to move to the previous and next menu respectively.

The +buttons are used for settings within a given menu.

Room sensors

6320Z04

For room temperature measurement, the internal or external room sensor can be

selected. The default is temperature measurement via the internal temperature sensor.

6320Z05

Slave On/Off

In a control loop with several room units, the temperature is measured in one device

only (the master). The LS flag (SL = 0) determines whether the room unit should

measure the temperature, or whether it is a slave device (SL = 1), in which case the

temperature sensor is disabled.

The default setting is SL = 0, i.e. temperature measurement active.

Further control loops can also be defined by means of a special application in the room

controller. In such cases, other room units can measure the temperature on the same

room bus.

Note

6320Z06

Offset correction

The error in an NTC 10 kΩroom sensor error combined with a measurement error

results in an error in the measured temperature reading. This can be corrected by

setting an offset correction value.

6320Z07

Measured temperature

This menu displays the current measured temperature including the previously set

offset correction value.

6320Z08

LCD display contrast

The LCD display contrast can be adjusted in this menu to suit different lighting

conditions.

Mounting instructions

To measure the temperature with the built-in temperature sensor, the HTC3.2/.. room

operator unit must be installed in a location suitable for room temperature

measurement.

Mounting location

This restriction does not apply if the temperature is measured with an external

temperature sensor. A suitable temperature sensor for this unit is the HSE1.1 cable

temperature sensor. If the VIMAR idea installation system is used, the room

temperature sensor HSE1.2 is also suitable.

STOP Important note Heat sources result in false temperature measurements. Ensure a minimum distance of

1.5 m from lamps.

6/10

Building Technologies HTC3.2/.. - Room operator unit CM2N6320en

01.09.2008

If the sensor is in an unsuitable location, the measured value can be corrected with a

temperature offset. The correction can be undertaken with the SCOPE or HSC (Hotel

Solution Commissioning) tool.

Correcting the

measured value

In the standard application the basic setting for the temperature offset is –4 K. This

applies to the room operator unit in cases where the temperature is measured with the

internal room sensor.

If a type HSE1.2 external sensor is used for temperature measurement, a temperature

offset of – 1K must be set.

•The HTC3.2/.. room operator unit should be mounted at eye level in the living area

of the hotel room.

•Lamps and other heat sources in the vicinity of the room temperature sensor must

not be allowed to distort the measured temperature. The room unit with the built-in

temperature sensor is not suitable for mounting within reach of the bed, for example,

because items such as bedside lamps cause too great an increase in the measured

temperature.

•Conduits must be sealed where they enter wall boxes, so that the temperature is not

falsified by draughts.

•To remove the device, it must be unscrewed from the wall together with the base-

frame.

•The screw terminals of the room operating unit can accommodate only one wire, with

a maximum diameter of 1 mm. When connecting the bus, therefore, we recommend

that the room unit should be connected as the last room-bus device.

•The device is intended for fixed installation in a dry, enclosed space.

•For installation in a 3-module mounting box, depth 50 mm

•Must be mounted horizontally only, with the front plate vertical

•Do not install AC 230 V devices in the same mounting box

•Commissioning must be carried out by trained personnel only

•Do not open the unit

•Local safety and installation regulations must be observed

Commissioning

To operate several devices connected to the same room controller, an address must be

set for each one (refer to "Engineering notes"). Only one device operates with the

factory-set defaults.

In the standard application with only one room unit, the defaults are ADR0=0, ADR1=0

and IE=1(internal sensor active). These are the factory-set values for the room operator

unit.

Note

Measured value corrections are carried out via the configuration menu or the SCOPE

or HSC tool, depending on where the sensors are located.
