What is Dataterm IHC?
Dataterm IHC is an intelligent heating control. It has advanced abilities which a
simple programmer and room thermostat cannot offer. It uses fuel economically
and is dedicated to your comfort.
How does it Work?
Dataterm IHC does the thinking for you, it has 30 inbuilt heating plans and the
facility for 3 individual custom plans. Simply choose one to suit your requirements
and your heating and hot water will be run efficiently for as long as you wish.
Using any one of the 3 custom plans Dataterm IHC will give you exactly the
temperature at the time required, with up to 8 set-points per day. This should cater
for the most demanding life styles.
What Next?
On the next page you will see how easy it is to put Dataterm IHC to work. The
built-in clock is already accurately set and needs adjusting only twice a year for
summer / winter time. Apart from that all you need do is choose a plan to suit
your needs and get it working.

How does Dataterm differ from an ordinary room thermostat?
It learns how your building responds to heating and cooling, and
uses this memorized data to avoid atmospheric variations.
How do I guess the `early start` time for my heating, to be warm when I get up?
You don`t need to any more. Dataterm will get you to within 10C of your set
temperature on time, to give you comfort without wasting your money.
Does this mean that Dataterm takes decisions away from me...so I`m not in control?
Just the opposite. Dataterm obeys `set-point` instructions, creating warmth at the
levels you choose, at times you dictate - offering up to 8 periods a day, without fuss.
Does this involve much complex plan programming, with so many possible variations?
No. There are 30 built-in plans, and the green section on the other side of this guide
shows how to get any plan working instantly.
How do I review or check all the set-point times & temperatures in these built-in plans?
You need to use the 'view' function of Dataterm: press the SELECT key, then the tap
symbol key, then the + key and the tap key again, you can view the set-points for any plan.
What can I do if none of these built-in plans are really suited to my needs?
Dataterm gives you the power to create (`edit`) your own personal plans, so you can store
three different custom built plans in the three memories provided.
What do the symbols on the Dataterm display screen mean?
Dataterm control is designed around three arrows - shown as small black triangles on
the screen. When a screen arrow flashes, for action just press the same shape key.
What can I do if I need help in the middle of adjusting Dataterm?
Easy. Use the HELP button, and the screen messages will steer you to safety. Because
they are context-sensitive, they relate to the topic you need help with.
Can I over ride a heating plan which is already running automatically?
Yes, at any time. Press the plus or minus buttons to change temperature temporarily,
and the heating plan will resume when the next set-point comes along
Does Dataterm start the heating at once when I ask for more warmth?
No. Dataterm uses advanced `fuzzy logic` which intelligently disregards short-term
fluctuations - so it takes adequate time to confirm a real change before switching.
What does the tap symbol mean?
In addition to planned hot water, pressing this button gives you an hour`s extra hot
water boost. Pressing it again turns the boost off. The screen shows what`s happening.
What else will Dataterm do?
Dataterm will protect your building from frost and can reduce condensation, depending
upon the heating plan you have chosen.
Is there any way of knowing how long my heating has been on?
Dataterm will give running totals for how long heating has been switched on. Simply
press the HELP key during normal operation.
Can I choose temperatures to be shown as Celsius (C) or Fahrenheit (F)?
Yes. However, this is an adjustment which you should ask your installer to arrange
to be carried out for you.
Who do I contact for help or advice with Dataterm?
The HELP button displays a series of screens: the last one gives a 'phone help number.
