Should I use wired or wireless TRV’s?

Wired TRV’s are always the best and most reliable option, if that’s possible?? Each wired TRV requires a thin 2 core, bell-wire type cable to be run between the radiator and HeatingSave controller. This is a simple and easy thing to do for new-builds and refurbishments; but more problematic for grade 1 or 2 listing buildings. Wired TRV’s are low voltage, requiring only 24 volts DC and they draw very little current. If you have several radiators in a room then you can wire these in parallel to one HeatingSave relay.
Remember, you can use a mixture of wired and wireless TRV’s on your HeatingSave system.

When to use wired TRV’s

  • Always, if you can?
  • New homes or refurbishments
  • When decorating rooms and wires can be installed
  • When laying a new carpet (tuck the cable under the skirting board)
  • Advantages

o No batteries to replace
o Very reliable, cable good for 100 years+
o Very good smoothing effect when heating rooms
o Inexpensive

When to use wireless TRV’s

  • Where it’s impossible to run a thin 2 core cable
  • Listed buildings or newly built/just refurb’ed rooms where you don’t want to mess up the decoration
  • Advantages

o Control heating where it would otherwise be impossible
o Email alerts when batteries need to be changed which means no surprises
o No wires
o Cheap to install but more expensive to buy
o Low power circuitry for longer battery life

HeatingSave has virtually no limit on the number of TRV’s that could be installed within your home.

How to use wired TRV’s

The wired versions require a single relay for each radiator or group of radiators and you can add T3516 sub units to each T3520 controller giving an extra 8 relays, 8 digital inputs for PIR’s, switches, etc., 8 analogue inputs for temperature sensors, light sensors, etc and ability to connect 2 off smart card readers. The number of T3520 controllers that can be connected to a system is almost limitless.

How to use wireless TRV’s

The wireless versions work on a Zig 2.4 Mhz wireless mesh network which can have up to 64,000 connections. The Zig 2.4 Mhz wireless mesh network can be extended using our T3526 range extenders.

Simple DIY installation

Unscrew the existing TRV by hand and replace with the HeatingSave thermostatic radiator valve head. For wired systems you need to have already laid the thin bell wire cable. The wireless TRV’s use the Zig 2.4 Mhz wireless mesh network to wirelessly “talk” to the HeatingSave controller. Both allow you to retro-fit HeatingSave to your existing heating system.

At the touch of a button, you can easily turn down (or switch off) the heating in rooms that you’re not using. You can also plan in advance for times when the heating will not be in use with the Heating Dairy when planning holidays. A ‘hands on’ override button on the wireless TRV’s means quick changes are easy from within the room, or better still just use your mobile phone App.

  • Low cost, simple to install and use
  • Setup all valves wirelessly from the HeatingSave web-based software, using your smartphone/tablet PC/laptop
  • Built in memory to match your lifestyle – each valve remembers patterns and future holidays
  • Quiet motorised valve, directly replaces traditional TRV’s
  • Automatic exercising when unused for 7 days to minimise seizing of radiator valves in warmer months
  • Compatible with most radiator valve bodies.

Heating Diary and Room Booking

Once you have the room heating under the control of your TRV’s you can use the Heating Diary and/or Room Booking system to manage the heating in each room. The difference between the TRV heads on your existing radiators and the HeatingSave ones is that the temperature set-point on our TRV’s can be controlled by you via your PC, mobile device or smart phone. There is also a ‘heat me now’ boost feature and the ability to cancel a heating period, just on the click of the App.
Manual TRV’s require you to constantly go into a room and manually twist it to change the temperature set-point. Let’s face it – this is unlikely to happen? and if it does, you will often forget to do it.

Click on the software and select Heating Diary and Room Booking options to learn in detail how to control the heating in your rooms.
