HTC-1 Clock / Humidity & Temperature Digital LCD Instructions

Here are instructions for the HTC-1 clock / humidity and temperature digital LCD.

HTC-1 Thermometer

I own two HTC-1 devices and it has helped me monitor my indoor surroundings. A while ago I lost the instructions, so I sat down and worked out most of the basics, which I’ve provided below:

How to switch between Celsius (°C) and Fahrenheit (°F)

  1. On the back of the device, lift up the stand (support legs).
  2. Press the black button to switch between the different temperature scales.

I really like the HTC-1 and my devices are currently being used in a bedroom and lounge. I am able to monitor the effectiveness of my actions, such as opening a window, closing a door and adjusting the boiler. I don’t use the alarm function, but I do find the clock feature useful.

I own a digital thermostat, which is in my hallway. I live in a flat and it’s interesting to see the temperature differences between a bedroom, hallway and lounge.

A cheap device, but it has made a huge difference.
