• Make sure all electrical power is turned off before filling water to the system. • Close all domestic hot water faucets. • Open main cold water supply valve and purge valve slowly. If water leaks from the
purging valve, close the valve immediately. • Before connecting the electrical wires, strongly recommend to do water leaking test
with/without a pressurizing pipe system. When the system tests with pressurized air, the test pressure should not exceed 50 PSI. Before testing, check the pressure relief valve and see if it is in the test pressure range. The shut off valve to the expansion tank must be closed to prevent damages to it. After the test, open the shut off valve to the expansion tank.
• Turn on the power to both the unit and the thermostat for heating. • The Heating Box™ will start circulate water. Please check the purging valve to see
whether there is any air left in the system. • Above steps should be repeated until there is no air left inside the piping system.
WARNING The expansion tank comes pre-pressurized at 50 PSI (4 Kgf/Cm2). If necessary, adjust the pressure in the expansion tank to the anticipated system operating pressure.

If separate secondary circulator has to be used in the system, the secondary circulator can be connected to the External Pump Port from the control box of the Heating Box™ to properly relay its power as an independent circuit (activating Port, dip switch No. 5 must be ON position). When room thermostat is ON, secondary circulator is also ON continuously. The control relay activates the primary circulator until it turns off the heating mode. When primary loop temperature gets close to the default set temperature, primary loop circulator will stop and the secondary circulator will continue to operate. When primary loop temperature falls below 5°F from the default set temperature, the primary circulator will start operating again to maintain the default set temperature range.
There are many applications you can apply with the Heating Box™ including radiant in-floor, radiant baseboard, hydronic air handlers, snow melting system and more.
Domestic Hot Water Supply
The Heating Box™ always prioritizes domestic hot water supply in operations. The Heating Box™ has a built-in priority switch to prioritize domestic hot water supply. For an example when it detects a demand from the domestic side while the unit is operating for the space heating side, it quickly switches over from the space heating mode to the domestic heating side by stopping a pump and/or a fan for the air handler until domestic hot water demand stops.

This Heating Box™ is designed to make a combination system (heat potable water and space) with just one heat source in convenience of simple installation. The unit consist with a high head bronze constructed pump to circulate water and built-in priority device for more effective distribution in domestic hot water. The Heating Box™ will make sure there will be no interruption to your domestic hot water even when the heating box is distributing its hot water to the space heating side. It supports domestic side fully as soon as it detects a demand from the domestic side and once the domestic hot water demand is done, it switches back to the space heating side until the room temperature reaches at its setting temperature. Also, its computer board monitors water movement and temperatures for both heat source and space heating to make steady and optimum performances.
The Heating Box™ can operate with any water heating systems offer in the market. The unit recommends the incoming water temperature from the heat source to be above 167 °F. After setting the temperature from the heat source, it needs to be entered into the computer board of the Heating Box™ for a proper control of each application. You need to set the temperature of the heat source into the computer board of the Heating Box so it control and distribute hot water to each application more effectively. In order to set the temperature, use dip switches and they are located on the front of controller in the Heating Box™. For heat source temperature between 158 °F – 167 °F, leave the dip switch settings at the factory default setting which is 158 °F.
* Above picture shows Space Heating’s return temperature and Dip Switches.

Domestic Hot Water Supply Whether the Heating Box™ is in stand by mode or space heating mode, domestic hot water supply mode is the priority. The whole system of Heating Box™ does act like a water heater. When you open a hot water tap, city water passes through the Heating Box™ to a water heater and produced hot water passes through the Heating Box™ to supply domestic hot water as you demand. The Heating Box™ monitors incoming hot water temperature from the water heater to make sure hot water temperature is in its setting range. The Heating Box™ has a built-in thermostatic mixing valve to set the domestic hot water supply temperature. The factory set is at 110 °F for domestic hot water supply and the Heating Box™ tries maintain the set temperature if incoming hot water from the water heater is above the thermostatic mixing valve setting. Domestic hot water temperature can be easily adjusted at the mixing valve.

Domestic Hot water temperature adjustment mixing valve
WARNING Over 122°F (50 °C) water temperature is dangerous to human body and it cause scalds and burns resulting in serious personal injury and/or death. Typical factory set temperature for domestic hot water is 120°F.
Space Heating
Whether using radiant heating or hydronic fan coil heating, simply turn on the room thermostat. The Heating Box™ controller will turn on the circulating pump and the heat source will supply hot water to the space heating appliance. The Heating Box™ has a built in thermostatic mixing valve to adjust space heating water temperature. Space heating water temperature is typically recommended at 120 °F for a radiant space heating and above 140 °F for a fan coil space heating. The Heating Box™ continuously monitors the temperature of space heating and returning water temperatures. The temperature range of the mixing valve on space heating side is from 86 °F (30 °C) to 140 °F+ (60 °C+). At the maximum temperature setting of the mixing valve, the valve fully opens and will allow the heat source temperature directly in to the space heating side.
Space Heating Supply Temperature adjustment
In the process of initial set up for a radiant heating or a fan coil space heating, LED from the control board will show each temperature read so you can easily identify and adjust flow rates and temperature drops.
20
Freezing Protection
The Heating Box offers two different freezing protection systems. One continuously check incoming city water temperature and when its temperature reaches below 6°C (42°F), the Heating Box’s pump will turn on automatically until the temperature of inside water pipe reaches to 20°C (68°F). It runs for about two minute.
Pump Exercise
Pump will run pump exercises for about 30 seconds at the point of non-usage in the period of 24 hours.

Design Reference for Heat Loss Calculation
This section gives a general idea to design a space heating system; it can vary system to system and case by case. Initial step in any heating system design is to determine the heating requirements (same as “heat loss”) of each individual room or area. More accurate heat loss calculation is to assure the potential of maximum energy savings and to achieve maximum level of comfortness. By using the conventional heat loss calculations for radiant heating design can result to over size the system. As an example, when desired room temperature is 65 °F ~ 70 °F and ambient temperature is -10 °F at seasonal low temperature, following resistance to heat flow values can be used for basic heat loss calculations in each construction site.

From above table, factor in areas as square feet to figure out heat loss calculation (or required heat calculation and unit for the heat requirement is BTU/hr in each section. Pipe spacing in a radiant floor heating installation can directly affect the heat output. The commonly recommended pipe spacing is 8” ~ 9” with ½” PEX pipe. Also the typical pipe lengths are from 150’ to 450’ in each loop where pipe lengths can be calculated (in each loop, heating area times by 1.3). For an example, if heating area is 200 square feet, pipe lengths are approximately 260’. Finally calculating the each loop requires flow rate divides by the total required heat output (BTU/Hour) by 500 times the design ∆T of the system. A design ∆T of 28 °F is considered optimum for on-demand tankless water heaters. Required heat output (BTU/Hr) each loop
Flow Rate = ━━━━━━━━━━━━━━━━━━━━ 500 X ∆T This is very rough formula to design a radiant heating system, please consult you’re your heating design engineer for more accuracy of your heating system design.
