OpenTherm provides more precise control on the boiler through the control of the gas valve. It allows the amount of heat provided by the boiler to be controlled to match the varying demand signal. By reducing the flow temperature to a minimum as it leaves the boiler, the return temperature is kept below the dew point (55°c) whenever possible, thus allowing the boiler to operate in condensing mode.
The OpenTherm can be used with the following OpenTherm capable Honeywell Heating Controls Sundial Pack RF2 Pack 5 and the Evohome Multi Zone Heating System.
Easy to wire
Simple binding to the appropriate control
Can be used to switch OpenTherm compatible domestic boilers

Your Right of Cancellation
You have the right to cancel the contract at any time up to 14 days after you receive the goods under the Consumer Contracts Regulations. Please note that this policy has some limitations which are detailed below and does not apply to business customers.
To exercise your right of cancellation you must give written notice to JTM Plumbing either via hand, post or email. Notification by telephone is not sufficient.
Except in the case of faulty or misdescribed goods, if you exercise your right of cancellation after the goods have been delivered to you, you will be responsible for returning the goods to JTM Plumbing at your own cost. The goods must be returned to the address as shown on the returns form. You must take reasonable care to ensure the goods are not damaged or the box defaced in any way in the meantime or whilst in transit. In the case of faulty or misdescribed goods JTM Plumbing shall, after receiving notification, either collect the goods from you or ask you to return the goods at an agreed cost which JTM Plumbing will pay for.
