SALUS HTRP24 Programmable Wired Digital Thermostat User Manual

SALUS HTRP24 Programmable Wired Digital Thermostat

Introduction

The HTRP24V(50) from SALUS Controls is a stylish and accurate 5/2 or 24h programmable electronic thermostat with a large, easy-to-read Liquid Crystal Display (LCD). It is surface-mounted temperature controller dedicated for surface heating/cooling, characterized by high thermal inertia. It is connected to the wired wiring centre KL08NSB. Thermostat has the function of creating your own schedules. It can control group (SLAVE) thermostats – via wiring centre it sends them an NSB (nighttime temperature reduction) signal and switches them to economic temperature. The time schedule is common to all thermostats (according to weekly (MASTER) thermostat), but temperatures are set individually on each thermostat. Thanks to the built-in algorithms, it offers much better temperature control accuracy than traditional mechanical thermostats. The thermostat is characterized by silent operation. The controller is characterised by silent operation.

Proper thermostat location

The ideal position to thermostat mounting is about 1,5m under floor level far from heating or cooling sources. In addition, the thermostat should not be installed behind curtains or other obstacles or in places with high humidity, as this will prevent accurate measurements of room temperature. The thermostat must not be exposed to sunlight. Do not place the thermostat on an outer wall.

Connection description

Note: The thermostat is compatibile with the following Salus wiring centre models:KL06 24V, KL08NSB 24V, KL04NSB 24V or directly to the actuator.

Symbols explanation

Montage

• Make sure that the thermostat is not connected to the 24V AC. Then open the front housing using a screwdriver as shown above.
• Connect the thermostat properly. Please refer to the “Connection description” section. Mount the thermostat using the designed screw holes.
• Slide the front of the controller over thermostat on the back of the controller cover. The thermostat is configured. Use or buttons to set the temperature setpoint.

Time and date setting

Set time and date during the first thermostat’s power up.

Manual mode – temperature setpoints

3 temperature levels are available. In manual mode, only one temperature level is maintained for the entire day. Icon in the frame indicates which mode is currently active. A different temperature can be set for each level.

• Comfort temperature mode
• Economic temperature mode
• Frost protection mode Usually used during the period of absence or during the holidays (only available in HEATING mode).

The thermostat also has 2 additional modes:

• The PARTY mode sets the comfort temperature for a user-defined time (maximum 9 hours 50 minutes).
• The HOLIDAY mode sets the frost protection mode for a user-defined time (maximum 99 days).

Press any button to highlight the screen, then follow the steps below:

Temperature setpoint
Press any button to highlight the screen, then follow the steps below:

AUTO mode – NSB function

The NSB (Night Setback) function enables automatic reduction of the temperature setpoint on the HTR24(20) SLAVE thermostat, via the HTRP24(50) programmable MASTER thermostat connected to the wiring centre (or other external clock). The temperature change takes place between the comfort temperature mode and economic temperature mode.
To activate AUTO mode, select the icon. Together with the icon, the thermostat shows the active temperature mode on the display: or .

Press any button to highlight the screen, then follow the steps below:

Note: For the proper NSB function work, an appropriate cable connection is required. The connection description is on the previous page.

Schedule programming

Press any button to highlight the screen, then follow the steps below:

Repeat steps 4 to 6 to set the time and temperature for further points of the schedule. No time (–:–) on the display means that thermostat will skip the time interval. 6 points are available for the schedule.

Heating/Cooling mode

Manual change:
Modes are indicated by symbols.
Press and hold button to enter the menu, then use button to select the Heating / Cooling mode change setting. Confirm changes using button. Now use or buttons to set the heating or cooling mode. Confirm by button.

Automatic change (via CO terminal):
The heating/cooling mode can be changed automatically via the CO terminal in the thermostat. If 24 V AC power supply is connected to the CO terminal – then thermostat automatically switches to cooling mode. If you want to use this function, then you have to change the value of the D18 parameter to “1”.

Cooling blocking:
When D19 thermostat parameter is set to “1”, then cooling is blocked for a single room. When the cooling function is blocked, no message is displayed.

Installer mode

Press any button to highlight the screen, then follow the steps below:

Note: To restore default settings – set the P47 code during 2 step and then confirm your choice using or buttons.
