My DRT1 Hortsmann works when you turn the temperature up. Turning it down i had to keep my finger on the button for a long time. Now it is not working. I have changed the batteries as well

The issue may not be with the Horstmann DRT1 itself but with the wireless version of the Horstmann thermostat, such as the HRFS1. The wireless model sometimes fails to resend signals if interrupted, causing it to continue heating or cooling without correction. Adjusting the thermostat temperature up or down past the actual room temperature and then back again can sometimes restore proper function. The hard-wired DRT1 is noted to be reliable.
