Honeywell DT90E Digital Room Thermostat - Replacement for the Honeywell DT200 Thermostat.

Features:

  • Energy saving TPI control
  • ECO button for energy saving mode
  • Simple user operation
  • 5 to 35°C set point range
  • 'OFF' setting with adjustable OFF setpoint
  • Direct replacement of the DT200 digital thermostat
  • Mains or low voltage switching
  • Two wire connection

The DT90E digital room thermostat has been designed to provide automatic temperature control of gas or oil fired boiler systems, underfloor heating, electric heating and zoning systems. Energy efficiency is addressed by state of the art control performance qualifying it as a Load Compensator. The DT90E has an ECO button energy saving feature which gives timed setback or boosts temperatures to reduce energy demand. This is a TPI (Time Proportional Integral) control product as defined in the Building Regulations, which make boilers operate more efficiently and provide close accurate control. The 'OFF' setting can be used for frost or hypothermia protection, assuming the system time control is also switched on. 'Installer Mode' allows control to be matched to the system and user requirements, adapting minimum on or off times, set point controls etc. Two wire, volt free connections are ideal for use with combination boilers or heating zones.

Question

Hello – In my flat I have a really simple thermostat to turn on/off the heating (Invensys combistar) and it is not working. I would like to upgrade with an electronic one. Could you please suggest a replacement for that? I took out the cover and I have notice that only to wires coming out from the wall.
Because I am renting the flat I don’t want to spend mega money for that.

Answer

Thank you for your enquiry - Please find product page link for a suitable non programmable digital room thermostat. Most newer room thermostats such as the DT90E are 2 wire thermostats.

Question

Hello – I am looking to replace my wired non digital room thermostat, with a wired digital type. I have looked on your site, but they seem to be only 2 wired. whereas, my existing thermostat is 3 wired . Can you tell me if this will still fit, or do I need a 3 wired thermostat. Thanks in advance.

Answer

Thank you for your enquiry - Most newer room thermostats such as the DT90E are 2
wire thermostats which means that the earth wire has to be made safe.

Question

Hi - I currently have a Potterton PRT2 Room Thermostat and would like to swap it for a Digital One.  All I want from the new Thermostat is a Set point and to be able to see the current room temperature.  The existing Potterton Thermostat is mains powered and has three wires (Red, Yellow & Blue).  I would prefer the new one to be mains powered as well.  Can you recommend a suitable Thermostat that I could basically swap like for like please?  I don't have a preferred Manufacturer.

Question

Hello! I am interested in buying a thermostat with an adjustable switch differential starting from ą 0.1°C (NOT ą0.2!) and higher. I was unable to find this kind of information (technical features and specifications for each thermostat) on your website. I would truly appreciate your help and advice.

Answer

Thank you for your enquiry - Unfortunately there are no room thermostats available with
an adjustable switch differential. Please find product page link for the Honeywell DT90E Thermostat
which has a Temperature control accuracy of 0.5°C (or better) at 20°C.
