Heatmiser IQ+, setting the standard for efficient space temperature control.

CANNOCK, U.K. - Sept. 8, 2013 - PRLog -- The Heatmiser IQ+ controller has been used in the heating industry for several years and continues to offer a value for money feature packed solution still not fully met by any other device.

At warmairheaters.com we now recommend the Heatmiser IQ+ Controller for every heater we sell, install or to those looking to upgrade their current heating control.

The controller is supplied in a strong plastic industrial enclosure and features a membrane keyboard which forms the whole front legend of the controller. The buttons operate well and provide a level of tactile feedback when they are pressed. The controller features an LCD display to show the current status of the heater and for programming. The front panel cleans easily and is ideally suited to both clean and dirty environments.

All aspects of the IQ+ controller can be pass code protected leaving very little that can be changed or modified without a code.

The IQ+ allows for three switching periods (on / off times each day) and is a true 7 day programmer. Separate day and night temperatures can be programmed into the controller and final space temperatures require a pass code to modify. Frost protection can be enabled in the device if required to protect pipework or stock in cold periods.

There are several operating modes and override modes available and the various options can be preset and locked into the controller to prevent unauthorised modification.

One of the many energy saving features of the IQ+ is the controllers self learning optimisation feature. Self learning optimisation puts the IQ+ in full control of your heating appliance and allows the controller to calculate how long it needs to operate to achieve your required space temperature. On colder days it starts the heating earlier and on warmer days it turns it on later. The time the heater is switched on is reduced and energy is saved. It can also be used as a conventional controller where occupiers prefer to turn the heater on when they arrive, rather than have the space to temperature on arrival.

A reset circuit is built into the controller which allows the controller to sense that the heater has locked out and can be configured to re-set the heater. This is a very useful feature when used with a suspended type heater, where the reset button is mounted on the often inaccessible heater.

As with all heater controllers a fan override option allows the heaters main fan to be turned on in the summer months to offer some levels of ventilation in the space and up to five holiday periods throughout the year can be defined for when the heater is not required.

The controller stores information about temperature, burner history and hours run for a period of 12 months and this can be displayed on the controller screen. This information can be used to calculate operating costs and is useful to service engineers when on site. The controller can be programmed to alert the user by means of a displayed alarm when a service is due, based on the number of hours the burner has operated.

One of the more advanced features of the IQ+ controller is its ability to operate a modulating burner. On a conventional burner assembly it can either be turned on or off. When a small amount of additional space heat is required a conventional burner assembly turns on full and satisfies the heat. When the space is heating up the burner assembly operates until the temperature is reached then it switches off. Control in this manner often suffers from overshoot and the space exceeds it's set temperature.

When coupled to a modulating burner, as the space approaches it's required temperature or set point, the controller signals the burner assembly to reduce its heat output. Control is normally achieved by a 0 to 10V DC signal applied to a modulating gas valve inside the heater.

This way the amount of gas used to achieve and maintain the space set point is reduced and this saving is made directly in the fuel bill by the end user. This feature can only be used if the appliance supports a modulating burner. The modulation parameters can be adjusted in the program to suit the appliance being controlled.

Some cabinet heaters feature high / low modulating burners which essentially have three modes of operation. Off, low fire and high fire. The IQ+ can easily be configured to support these types of burner for additional energy saving.

With the addition of a black bulb sensor, the controller and program can be configured to operate a range of radiant tube heaters. The controller can also be configured to use a remote sensor, has a fan proving input and fan controller relay to allow operation of a duct mounted unit. For basic operation the controller contains an accurate internal space sensor which is used by default. Additional remote warm air space sensors are available and can be added if required.

For sites with a number of zones (different spaces with different heaters), up to 30 IQ+ controllers can be networked together to provide an easy to use central control configuration. Each units control parameters are stored in the local controller so in the event of the network cable being damaged each heater will still function as last configured. Each IQ+ controller on the network can be allowed full access, locked to allow only local access or can be totally locked for no access at all.

Any IQ+ configured for full access can be used to program any other controller present on the network. A configuration created on a local IQ+ can be copied to all devices on the network if required, useful for global site wide updates. For minor changes, they can be done directly to a remote IQ+ or single parameters updated globally as required.

The IQ+ supports multi country zones and the operating language can be preconfigured on the device. We export warm air heaters worldwide and this feature is very useful, the manual supplied with the heater is also multilingual.
