PERRY 1TP-TE028B DIGITAL THERMOSTAT  

PRESENTATION

Dear Customer, thank you for choosing our product.
The thermostat, suitable for all heating and/or cooling system, is fitted with a large and clear backlit display to keep all its functions under control in real-time. The fundamental feature is its easy-to-use menu navigation, which makes it extremely user-friendly despite its comprehensive range of functions. The thermostat is factory-set to adjust temperature in a Differential ON/OFF manner and hysteresis can be set from 0.2°C to 1.2°C to adapt to the thermal inertia of your specific installation. Alternatively, modulating Proportional operation may be selected with settable duration cycles (from 7 to 20 minutes): this system ensures the desired temperature is maintained more stable, increasing user comfort and is particularly suitable for installations with high thermal inertia such as, for instance, for underfloor radiant panels. The set temperature scale is in degrees Centigrade (Celsius) with the option to calibrate room temperature measurement by setting a correction value (from -3 to +3 °C). The thermostat can be connected to a separate remote controllable temperature probe (optional) which may then be set according to one’s installation needs: remote, floor, external. Special attention was devoted to energy saving: pausing for household cleaning, optional Set temperature (MAX/MIN) lock, adjustable anti-freeze temperature value, and control through an external contact (e.g. optional telephone programmer), are conducive to avoiding wasting energy with consequent savings. See the following pages for a description of these as well as of other features

TYPE TEMPERATURE ADJUSTMENT METHODS

• The thermostat is factory set to work in THERMAL DIFFERENTIAL mode
• ON/OFF with a preset thermal differential value (Hysteresis) of 0,3 °C.

Note: adjustable from 0,2 °C to 1,2 °C (from 0,3 °F to 2,1 °F).

• The hysteresis value must be set according to the system’s thermal inertia; a low value is recommended for systems with radiators made of e.g. cast iron and a high value for systems with fan coils.
• As opposed to the thermal differential, the temperature can be adjusted MODULATING PROPORTIONALLY (PROP) setting cycles from 7 to 20 minutes (default 10 minutes).
• This system maintains the desired temperature more stable, whilst increasing the user’s comfort sensation and saving on energy consumption.
• A long cycle is recommended for systems with high thermal inertia (cast iron radiators, floor systems) and a short cycle for systems with low thermal inertia (fan coils).

CHANGE UNIT OF MEASURE FOR TEMPERATURE READING

The thermostat is pre-set in the factory to display temperatures in degrees Centigrade (Celsius), it is possible to switch to the Fahrenheit scale or vice versa with the following procedure

• Through the path CONFIGURE SEt ->selectUNIT SEt then pressOK.
• Select the desired unit of measure with the keys: °C or °F, then press OK to confirm.
• All temperature set points will be updated according to the new scale.
• Press the back key to exit.

CORRECTION OF ROOM TEMPERATURE READING
If for any reason the thermostat must be installed in a position where the measured room temperature might be affected (e.g. perimeter wall which is on average colder in winter and warmer in summer than the rest of the dwelling) the device has 2 separate parameters to adjust the room temperature measured in the Winter and Summer modes.

OFFSET for winter mode( )

• It is the display that alternates the empty fields to be inserted (- – – -) with the current temperature value.
• Use the key to enter positive values, and the key to enter negative values (sign «-»).
• Possible correction -3.0 °C (-5.4 °F)÷3.0 °C (5.4 °F) default 0.0 °C/°F=- – – –
• At each selection, the display will show the new correction value (e.g.: 0.6°C) alternated to the detected temperature value (e.g.: 21.2°C).
• After performing the correction press «OK».
• The display shows the OFFSET for the Summer mode ( ); proceed with the correction as per the above procedure or press back to quit

MAX AND MIN SET TEMPERATURE LOCK (Winter and Summer mode)
In certain thermostat installations (public buildings, hotels, etc.) it might be useful to limit the maximum and minimum temperature set points. This avoids incorrect settings by unauthorized personnel (energy savings). It is possible to limit (lock) the maximum, minimum, or both temperature values settable on the thermostat. The restriction may be applied either to the Winter or summer mode.

• From normal thermostat operation, access the menus by pressing and holding the «Menu» key.
• Through the path CONFIGURE SEt ->, select item LOCKS SEt. Press OK to confirm
• In a sequential manner, it is possible to set maximum temperature locks (t1 comfort) and/or minimum (t2 economy) for the winter mode and/or maximum temperature (t1 comfort) and/or minimum (t2 economy) for the Summer mode.
• If no locks have been entered yet, the display shows empty flashing fields (- – – -).
• Use the keys to set the desired temperature lock values from time to time.
• Upon completing each setting pressOKto confirm and move to the next lock item.
• Press the OK impulse key to move to a different item. Press the back key to exit.

General rule

• If Set temperature t1 (comfort) is greater than the maximum entered lock, it will level out with it.
• If Set temperature t or t2 is less than the minimum entered lock, it will level out with it.
• The following rule will apply to all other temperatures: WINTER ( )=t1>t2>t – SUMMER ( )=t1<t2

PROBE MENU
In addition to the internal probe of the thermostat, it is possible to connect to terminals 6 and 7 «AUX 1» (see wiring diagrams in ch. 5.4) a supplementary probe (optional) which may be set to read temperature in various modes.

Press the back key to exit.

• Internal probe reading range: – 5.0°C ÷ +37.7°C (+ 23.0°F ÷ +99.9°F)

SETTING SEPARATE REMOTE PROBE

This is a remote probe to detect the temperature in a different room from the one where the thermostat is installed, for instance in the event of unfavorable installation or in premises unsuitable to reading and adjusting the temperature. The remote probe has the same parameters and reading range as the internal probe. Reading range: -5.0°C÷+37,7°C (+23°F÷+99,9°F). It completely replaces the internal thermostat probe and the product will control room temperature through this remote probe. After connecting the remote temperature probe to the thermostat, it may be activated through the path: Menu key for 3 secs. ->CONFIGUR Set ->PROBE SEt ->select itemREMOTE. Press «OK» to confirm. Press the back key to exit

SETTING FLOOR PROBE

This is a separate and remote controllable temperature probe, buried in the screed of an underfloor heating system with radiating panels, to monitor the temperature and turn off the system in case the temperature read exceeds a pre-set threshold value. After connecting the separate temperature probe to the thermostat, it may be activated by holding down the Menu key for 3 secs.->CONFIGUR SEt ->PROBE SEt ->select item FLOOR. Confirmwith the OK key.

• Press the back key to exit.
• Floor probe reading range: + 0.0°C ÷ +60.0°C (+ 32.0°F ÷ +140.0°F)

The thermostat displays and controls the room temperature detected by the internal probe:
at the same time the separate probe also detects the floor temperature, which will be compared with the threshold set by the installer, to prevent this temperature from exceeding the safety threshold. Should this occur the thermostat will switch off the system even if Set t temperature is not reached; the display signals this condition by displaying the code tP and the set threshold value flashes

SETTING SEPARATE EXTERNAL PROBE

This is an additional probe to read the temperature outside the dwelling (tE). It does not have any home temperature control features, which are controlled by the internal thermostat probe After connecting the  external temperature probe to the thermostat, it may be activated by pressing the Menu key for 3 secs. and through the path CONFIGUR SEt ->PROBE Set ->select itemEXTERNAL.
