Room Thermostat needs to be placed in the room which is used most  

frequently. For instance; living room or lounge. Placing the Room  

Thermostat in a spot that have air circulation like entrance of a room  

or side of window should be avoided. Also anywhere close to  

heating/cooling units such as radiator, stove and spots which get  

direct sun lights would not be suitable. Room Thermostat needs to be  

located above the floor 150 cm height. Few trials may be made to find  

themost convenientspot.

After completing the cable connection process, firstly turn on your fuse  

and then yourheating/cooling unit.  

TPIROOMTHERMOSTATWORKINGLOGIC  

Dimensions  

90mm / 90mm / 25mm  

230V AC  

Your Room Thermostat works with the TPI algorithm. Room  

Thermostats using TPI technology predict when the temperature of  

your home will rise above or below the set temperature and turn the  

heating / cooling unit on and off accordingly. This ensures that your  

home stays at the temperature you set without maximum deviations  

up and down.

By pressing the Receiver's manual usage button for 2 seconds, youshould  

see the Orange Light blinking on the Receiver. In this way, after making  

sure that the heating/cooling unit is operating, press the same button  

again for 2 seconds and seethattheOrangeLEDturns off.  

Set up the Room Thermostat to pair the Receiver with the Room  

Thermostat.

GENERAL LIFE MITRA 250S RF Digital Room Thermostat User Manual Overview

Summary of Contents

• Page 1: Battery placement is essential for the digital room thermostat. The user can adjust the room temperature for more comfortable heating and cooling. If the cooling indicator is blinking, the cooling unit is working; if steady, it is not. Heating calibration is necessary for accurate temperature control. The receiver and room thermostat must be paired for proper operation. Low battery warning indicates the need for battery replacement. Temperature calibration may be needed for accurate readings. The receiver should be placed away from heating/cooling units and electronic devices. The room thermostat should be located at a height of 150 cm above the floor. The TPI algorithm ensures stable temperature control by predicting temperature changes.
• Page 2: warranty conditions outline the coverage for manufacturing defects for 5 years from the invoice date. tpi technology ensures optimal energy efficiency by measuring and applying the best timings to maintain the desired temperature. devices are delivered in working condition, with on-site commissioning subject to a service fee. repairs under warranty are conducted at the company factory, with transportation costs borne by the customer for on-site services. maintenance of devices is also performed by the company, with travel expenses covered by the customer. the tpi room thermostat adapts to temperature changes and learns how to maintain the desired room temperature efficiently. if the placement of the tpi room thermostats is changed, the learning process restarts and takes about 7 days. malfunctions caused by customer misuse are not covered by the warranty, and all expenses in such cases are the customer's responsibility. the warranty is void if devices are damaged by the customer or if they are used contrary to the user manual. customers can appeal to consumer courts regarding warranty disputes, and the warranty document must be retained throughout the warranty period.
