Condensing Boilers High efficiency wall hung condensing boiler with ultra low NOx emission QUINTA RANGE OUTPUTS Q30: 5.6 - 28 kW Q45: 7 - 40 kW Q65: 11 - 61 kW Q85: 14.4 - 84.
Introduction Remeha Quinta Range are compact wall hung condensing boilers. Lighter and more efficient, their small dimensions make them ideally suited for modular arrangements. An optional optimising/ weather compensating control system is available to ensure maximum efficiency. The boilers can be installed on both new and retrofit installations. Boiler description The Remeha Quinta Range are wall hung, condensing boilers which may also be installed free standing on a suitable frame (option).

Advantages at a glance • High efficiency: 110% NCV at 40/30ºC (99% GCV) • Boiler control: a) Modulating (18-100%) b) High/low (18-100%) c) On/off • Premix burner for clean combustion • Low NOx < 25ppm (02=0%, dry) • Quiet operation <48 dBA • Digital display Operating principle Combustion air is drawn into the closed air box, by a variable speed fan, through the air inlet connection from the plant room (open flued) or from outside via the concentric flue system (room-sealed).

General Low water protection (flow and content) The Remeha Quinta Range is supplied as standard with electronic control and flame ionisation safety controls, with a specially designed microprocessor at the heart of the control system. The Remeha Quinta Range are supplied with a low water protection on the basis of temperature measurement. By modulating back at the moment that the water flow threatens to fall too low, the boiler is kept operating for as long as possible.
Boiler control The Remeha Quinta Range can be controlled using one of the following methods Modulating (two wire control) When using the optional Remeha compensating controllers the heat output modulates between the minimum and maximum value on the basis of the boiler flow temperature sensor. This applies to both single and multiple boiler installations, under the dictates of a room and/or outside temperature sensor. Celcia 20 - Optimising room/outside weather compensating control for single boiler.
Frost protection Temperature control Install the boiler in a frost-free room. The builtin frost protection system is activated as follows: Below 7°C - system pump is switched on if connected to boiler. Below 3°C - boiler is switched on, when the flow temp reaches 10°C the boiler and pump switch off. With a Remeha temperature sensor or with a standard (volt free) DHW thermostat. Note: will only provide a setting and read out facility with the sensor option.
