Intronics Digital Room Thermostat User Guide -

This device is an electronic temperature controller designed to replace older mechanical thermostats. It provides precise temperature control for central heating systems.

In "Off" mode, the thermostat usually retains a frost protection setting. It will not allow the room to drop below 5°C (41°F). Do not manually override this by disconnecting power if the building is unoccupied during winter.

and PI series, is designed for precise temperature control in mini-split, duct-type, or chilled water systems. These devices feature back-lit LCD displays and Proportional + Integral (P+I) control for optimal comfort. Core Operation Guide

Power On/Off: Press the power button to toggle the unit. When turned on, it typically defaults to the last saved program setting.

Temperature Adjustment: Use the △ (Up) or ▽ (Down) keys to set your desired temperature. The standard set-point range is 10°C to 35°C (50°F to 95°F).

Fan Speed Selection: Cycle through the three available fan speeds (Low, Medium, High) using the designated fan or mode button.

Mode Selection: Depending on the model, use the Mode button to switch between Cool, Heat, Dry, or Auto functions.

Energy Saving (Econo): Activate the Econo function to optimize energy usage, which often sets the temperature to a pre-defined energy-efficient level (e.g., 18°C).

Turbo Mode: Use the Turbo function for rapid cooling when the room is initially too warm. Advanced & Installer Settings

To access deeper configuration menus for system protection and calibration:

Enter Setup: Press and hold the △ and ▽ keys simultaneously for 10 seconds. A dot or specific indicator will appear on the display. This device is an electronic temperature controller designed

Navigate Menus: Use the △ key to advance through program numbers and the ▽ key to change parameter settings. Key Settings: Calibration: Adjust temperature display accuracy.

Frost Protection: Sets a minimum temperature (default 10°C) to prevent pipes from freezing when the unit is "Off".

Compressor Delay: Protects the compressor by preventing rapid cycling.

Exit: Press the power or escape button to save and exit the installer menu. Installation Basics

Wiring: Use 0.5-1 sq. mm cable size. Ensure the AC mains supply is kept separate from signal wiring to avoid interference.

Mounting: The backplate is separable for easier installation. Secure the backplate to the wall before snapping the front case into place.

Remote Sensor: Some models support an optional external room sensor for more accurate readings in large or wet rooms. SERIES Digital Room Thermostat II INSTALLATION MANUAL

This guide provides the necessary steps for installation, operation, and advanced configuration to ensure your system runs efficiently. 1. Key Features and Models In "Off" mode, the thermostat usually retains a

Intronics thermostats typically feature Proportional + Integral (P+I) control, which minimizes temperature fluctuations compared to standard on/off controllers. PI02 Model : 24 VAC floating digital thermostat. PI04 Model : 24 VAC/VDC modulating digital thermostat. Series II LED/LCD

: Versatile units for fan coil systems, available in 24V, 120V, and 220V versions.

Standard Features: Backlit display, 3 fan speeds, compressor time delay, and non-volatile memory (EEPROM) that saves settings during power loss. 2. Installation Guide

Warning: Only trained technicians should perform the installation to avoid damaging the heating or cooling system. Mounting Location

For accurate readings, mount the unit approximately 5 feet (1.5m) above the floor. Avoid placing it: In direct sunlight or near heat-producing appliances. Near drafts, doors, or windows. On exterior walls. Wiring and Mounting

Disconnect Power: Turn off the main breaker to the HVAC equipment before starting.

Separate the Backplate: Use a flat-head screwdriver to unlock the snaps at the bottom of the thermostat and pull the backplate away.

Connect Wires: Use 18-22 gauge wire. Follow the terminal designations on the back of the unit. Ensure connections are firm.

Secure Unit: Screw the backplate to the wall using the provided anchors and snap the thermostat body into place. 3. Operating Instructions

Once installed, the basic operation of an Intronics thermostat is straightforward. Intronics digital room thermostat user guide
