GENERAL MITRA 250S Digital Room Thermostat User Manual Overview

Summary of Contents

• Page 1: Room thermostat needs to be placed in the room which is used most frequently. Placing the room thermostat in a spot with air circulation or close to heating/cooling units should be avoided. Room thermostat needs to be located above the floor at a height of 150 cm. MITRA 250S is a wired room thermostat that allows users to adjust room temperature for comfortable and economic heating/cooling. Operations within the heating/cooling unit or electrical installation must be carried out by professionally qualified persons. Temperature sensors in room thermostats are highly sensitive and may require calibration for accurate readings. Your room thermostat has heating and cooling modes that can be switched easily. You can reset your room thermostat to its default factory settings, which resets calibration and heating/cooling modes. When the low battery warning icon appears, it is recommended to replace the batteries. If the cooling indicator is blinking, the cooling unit is working; if steady, it is not working.
• Page 2: Warranty conditions state that the warranty period starts from the invoice date and covers manufacturing defects for 5 years. The TPI Room Thermostat uses a learning process that restarts if the placement is changed or if the device is de-energized. TPI technology ensures energy efficiency by predicting temperature changes and adjusting the heating/cooling unit accordingly. Devices are delivered in working condition, and on-site commissioning incurs a service fee. Repairs covered by warranty must be conducted at the company factory, with transportation costs borne by the customer for on-site services. Malfunctions caused by customer misuse are not covered by the warranty, and damages from other brands or models are also excluded. The warranty document must be retained by the customer, and a replacement will not be issued if lost. The manufacturer confirms that the product complies with relevant directives and specifications. The average room temperature is calculated over the last 40 seconds to maintain desired temperature levels. Customers can appeal to consumer courts for complaints regarding warranty issues.
